Heavy metal pollution is a major problems in the environment. The impact of toxic metal ions can be minimized by different technologies, viz., chemical precipitation, membrane filtration, oxidation, reverse osmosis, flotation and adsorption. But among them, adsorption was found to be very efficient and common due to the low concentration of metal uptake and economically feasible properties. In this review paper, Fe–Mn binary oxide incorporated into diatomite (Fe/Mn-diatomite) was prepared by a simple coating method , and removal of Cu(II) from aqueous solutions. The effects of three independent variables including initial ion concentration, removal time, and adsorbent dosage were investigated on the maximum adsorption of Cu (II). The optimum conditions for the adsorption of Cu(II) was obtained: 75 ppm of initial ion concentration, 150 min of removal time and 1.5 g/l of adsorbent. The maximum removal efficiencies of Cu(II) was obtained 86.25%. The results showed that Fe/Mn-diatomite was apable of treating copper metal in wastewater.

Electric vehicles (EVs) making a significant contribution to the reduction of fossil fuel consumption and CO2 emissions are expected to thrive in Vietnam in the upcoming years/in the near future. However, such vehicles’ energy demand could become a burden on the transmission networks, causing overloads to the electric grid of the nation. Hence, to solve this problem, a solar PV system can be utilized to fulfill the electricity needs in an EV charging station. This article presents the design, simulation and economic analysis of a grid-connected solar power system for an electric charging station at Thu Dau Mot University (TDMU). The photovoltaic (PV) power system is designed to supply energy to the charging station and office building. The study estimates the generated electricity, the efficiency of the PV power system and the ability to reduce CO2 emissions. This paper can be a recommended input for stakeholders to consider using this energy source for charging vehicles.

The paper demonstrates the role of globalization and localization in the process of Vietnam’s interaction and integration with other cultures, causing changes in Vietnamese language. Globalization is defined as the free movement of goods, services and people of the worldwide scope across the borders of countries, resulted from the opening up of the global economy and advances of technologies. The increasing interconnectedness and integration of the economies of the world furnish more influx of information among countries which do not have anything in common and Internet and social media well contribute to such spread. Not only the pros but the cons of globalization are used to explain the part of localization as the entire process of adapting a product or content to a specific location or market. The paper indicates localization as the Vietnamese people’s endeavor to adapt Vietnamese language to the world while protecting and enhancing the national characters. The differences between localization and globalization are analyzed to demonstrate the value and requirements of localization in the present time. The influences of Sino-Vietnamese and French language are also found out as evidences of the phenomena. The changes of Vietnamese language from globalization and localization are illustrated with devices, ideas and images referring to the objects, actions or ideas.

This paper examines the main challenges of the processes of space and social policy change present to current urbanization trends of Taiwan. The chapter argues that one of the main challenges is economic growth, increasing integration into the global economy and making Taiwan competitive in the global economy. This process leads to the growth of large urban regions that present many challenges to the urban development in the future. In particular, the paper focuses on the most fragile areas of the extended urban spaces are the rural and urban margins, where urban activities are expanding into densely populated agricultural regions. It is argued that in these areas, local policies should be developed that adapt to local ecosystems. The paper presents lessons of interventions in this field for Ho Chi Minh, Dong Nai and Binh Duong Region for urban expansion.

Youth in a nation is the most viable and potential human resource in both demographic and social structure. Without the youth's adequate and integrated bio-social development a nation cannot attain its anticipated human goals. Based on government initiative a2i, the empowerment of youth towards sustainable development in Bangladesh is described in this paper. Although the Bangladesh Government has formulated and implemented policies, plans and programs for youth welfare are still through GOs and NGOs. Related literature indicates that, regardless of all age and regions, young people in this country face several socio-cultural problems where they cannot grow and empower themselves adequately. As a result, they cannot play their important roles in sustainable development and changes within the country. To resolve the problems of the youth in relation to their development and empowerment, the Government of Bangladesh is developing and implementing some solutions. The case study focuses on the role of a2i for development of youth in the successful design of public development and sustainable development programs.

Activity recognition is one of the preliminary steps in designing and implementing assistive services in smart homes. Such services help identify abnormality or automate events generated while occupants do as well as intend to do their desired Activities of Daily Living (ADLs) inside a smart home environment. However, most existing systems are applied for single-resident homes. Multiple people living together create additional complexity in modeling numbers of overlapping and concurrent activities. In this paper, we introduce a hybrid mechanism between ontology-based and unsupervised machine learning strategies in creating activity models used for activity recognition in the context of multi-resident homes. Comparing to related data-driven approaches, the proposed technique is technically and practically scalable to real-world scenarios due to fast training time and easy implementation. An average activity recognition rate of 95.83% on CASAS Spring dataset was achieved and the average recognition run time per operation was measured as 12.86 mili-seconds.

The paper presents general theory about making small models for studying large machines. Here, the author refers to the design of pile driving and pressing machines. To express ideas, the author presents design drawings presented in three-dimensional perspective. Currently, pile drivers and pile presses are two separate machines, in which their base machine is the same, their working parts are slightly different. The author takes advantage of the slight differences to combine them into one machine, so as to ensure that this machine is able to pile or pile. In addition, the structure of pile making and pressing machines is created by the author, which is somewhat simpler than the current construction and driving machine. This successful study will form the basis for manufacturing a pile driving machine and pile machine into a single machine, greatly reducing the costs of procurement and construction machine use.

Variable Frequency Drives (VFDs) are electronic power controllers that allow for accurate control of the speed of alternating current (AC) induction motors that used in many kinds of machines including fans, pumps and compressors. These motors are used in most heating, ventilation and air-conditioning (HVAC) systems and account for a significant percentage of the total HVAC energy consumption. More efficient operation of these motors using VFDs can result in significant energy savings. Besides, the communication between VFDs and PLC for Supervisory Control And Data Acquisition (SCADA) is also important. Modbus protocol has many kinds as RS485, RTU, Profinet,...In this paper we will present the communication between a PLC Siemens S7-1200 and an ATV310 Drive (Schneider) via Modbus RTU protocol which is supported.

Across the world, the first accounting course provides serious challenges for teaching. These arise from powerful negative perceptions which include the anxiety associated with tertiary-level study and the differing backgrounds or majors of students required to take the course.

This research aims to describe English language errors in the scientific papers. The research data consists of 104 scientific articles that authors sent to Journal of Thu Dau Mot University. The quantitative method was applied in the form of frequency charts for each category of surface strategy taxonomy and comparative analysis. Based on the analysis theory of grammatical errors, all of the errors in these articles were identified and classified into different categorizations. The findings of the study showed that the authors’ writings were committed three main error groups: Lexical errors are the highest with 281 (49%); the number of Syntactic errors are ranked the second with 222 (39%); Morphological errors are the lowest with 69 (12%). On the basis of these results it is figured out that the authors still have difficulties in writing a research papers in English because they are not English major. Moreover the grammar of English is known as their foreign language. Another reason that the writer made errors is uninterested in organization of their papers. From the study findings above, the researcher suggests some implications to help authors improve their academic writing and meet English international standard.

Binh Duong has rapidly transformed during the period 1999-2009, from a agricultural province to industrial one. The paper explores the shift of occupation-based social structure of Binh Duong during that period. Using the data sets of Census 1999 and 2009, the paper analyses the evolution of the occupational figure in Binh Duong by ten occupational categories and four occupational strata, and the differences in this figure by residence, gender, ethnic, and religious variables. Findings show that the occupational structure of Binh Duong is more developed than the one of the Southern Key Economic Zone. Its change in rural areas is more significant than in urban areas. There are not considerable differences by gender, ethnicity, and religiousness. The findings are suggestive for a further analysis using the data set of Census 2019 on the evolution of occupational figures in Binh Duong during the previous twenty years (1999-2019).
