Antimicrobial resistance (AMR) is a threat to animal and human health globally. Antimicrobials are used in aquaculture to control different bacterial diseases. However, inappropriate use of antimicrobials can accelerate the emergence of AMR. This study was conducted to determine antimicrobial resistance in Streptococcus agalactiae, which affects and causes diseases with high mortality in tilapia. A total of 26 S. agalactiae isolates were streaked from kidney/brain/liver samples of diseased farmed tilapia from 2017 to 2021 at Hai Duong, Bac Ninh, Hoa Binh, Yen Bai provinces. The sensitivity of the isolates to 7 antimicrobials was established by disc diffusion (Oxiod). The results showed that levels of resistance vary from S. agalactiae to DOX (34.4%), RIF (64.1%), TET (45.0%), ERY (64.8%), TMPSMX (70%), FLO (35.3%), and AMP (75%). The resistance rate to DOX was significantly different (p<0.05) compared to ERY. S. agalactiae has the highest resistance to 2 types of antibiotics at 19.2%, followed by resistance to 3 types (15.4%), and resistance to 6 and 7 types of antibiotics at a rate of 11.5%. The resistance in 1 type, 4 types, and 5 types of antibiotics was observed lowest at 7.7%. Vietnamese tilapia farmers need guidelines for effective antimicrobial treatment and wwider take up of vaccine or sustainable farming technology to prevent infections caused by S. agalactiae and reduce emergence of AMR

Published: June 2024

In the context of fundamental and comprehensive reform of education and training, in addition to innovating teaching content and teaching methods, changing moral education of students through positive discipline also receives great attention. Positive disciplinary education contributes to the comprehensive education of students' personalities, meeting the requirements of society. Survey results show that awareness of positive discipline education for students in high schools, besides the positive aspects, still has certain limitations. To contribute to the formation of a “Happy school” and comprehensively improve the quality of education, awareness of administrators and teachers in high schools needs to be improved about positive discipline education.
IMPROVING THE EFFICACY OF NETWORK SECURITY BASED ON DIMENSIONALITY REDUCTION TECHNIQUES
Authors:   University of Economics - Technology for Industries, Hanoi, Vietnam, Thi Phuong HOANG
Published: June 2024

This paper focuses on proposing a network intrusion detection model applying fundamental machine learning techniques to enhance early detection of network intrusions (rapid detection of attack behaviors) for improved efficiency in preventing network attacks. The system must still ensure technical accuracy in providing high-precision alerts. The research employs several dimensionality reduction techniques to detect abnormal network intrusions caused by Distributed Denial of Service (DDoS) attacks. The proposed model aims to reduce computation time for early attack detection. The results show that the proposed system performs best across all three datasets through the combination of the KNN algorithm and the Feature Importance dimensionality reduction technique. After calculating and returning the number of important features in attack detection using the Importance technique, the performance of the KNN algorithm is enhanced. By retaining only important features, as the dimensionality of the data decreases, the computation speed of KNN increases. Therefore, although the accuracy may slightly decrease, the computation time is significantly reduced. This is acceptable for practical purposes.

Published: June 2024

In recent years, with the strong development of information technology, detecting communities in large real networks is a very important issue which is of interest to many scientists. Community detection in large real networks with millions of nodes is often difficult. To solve this problem, many online community search algorithms have been proposed with many different approaches. One of the approaches is to coordinate the vertices of the graph and build a reasonable distance between those vertices. It has been observed that vertices in the same community have approximately the same probability of reaching other vertices through a random walk. Based on this principle, the authors propose a way to coordinate vertices and build distances between vertices in the graph that reduces computational complexity compared to existing techniques. This approach involves representing peaks as vectors and using the Kmeans++ algorithm for community detection, whose effectiveness is evaluated through experimental results presented.

Zinc oxide (ZnO)-based varistor ceramics, incorporating varying amounts of Y2O3/CeO2, were fabricated through a twostep solid-state reaction method involving pre-calcination and subsequent sintering processes. ZnO powder and corresponding additives served as raw materials in the production. The investigation of phase composition, microstructure, and electrical properties employed techniques such as X-ray diffractometry (XRD), scanning electron microscopy (SEM), and direct current electrical measurement. The findings revealed that varistor ceramics sintered at 950°C, using powder pre-calcined at 800°C and doped with an appropriate amount of Y2O3, exhibited enhanced electrical properties. Conversely, the introduction of varying concentrations of CeO2 did not contribute to the improvement of the electrical characteristics. The CeO2-doped samples displayed lower breakdown voltages and nonlinear coefficients compared to the undoped sample (M0). The addition of Y2O3 proved effective in improving the nonlinear coefficient but resulted in a decrease in the breakdown voltage withstand capability of the samples. A Y2O3 content of 0.5% was identified as a suitable compromise, balancing both factors. Notably, ZnO varistors doped with 0.5 mol% Y2O3 demonstrated optimal comprehensive electrical properties, featuring a breakdown field of 620 V/mm and a nonlinear coefficient of 45. These results suggest that Y2O3 doping holds promise as a viable strategy for achieving varistor ceramics with outstanding electrical performance.

Teaching and learning under the credit-based system has become widespread in the higher education system of Vietnam. The assessment of learning outcomes through credit-based education not only relies on the foundational knowledge accumulated in the classroom but also evaluates the process of self-study and research of learners. Besides spending time studying and researching at the university, students are required to allocate a significant amount of time to conduct self-research and participate in group discussions to address issues related to the subject matter. Although most students demonstrate a high level of self-awareness during the learning process, there are still instances of a lack of self-awareness. Recognizing this issue, the question arises: how to guide students to apply self-research methods effectively and how to objectively evaluate the results of the self-research process? Drawing on practical experience in teaching the Computer Networking course under the credit-based system for students of the K22 cohort, belonging to the Faculty of Information Technology, Thai Nguyen University of Information and Communication Technology, the authors have conducted exchanges and proposed methods, organizing techniques, and assessment tools for evaluating the results of the self-research process of the course content, aiming to enhance the quality of education and encourage students to actively engage in the learning and in-depth research process.

Contribution to the Erebidae of Jordan (Lepidoptera: Erebidae)
Authors: Katbeh-Bader A.
Published: June 2024

The Erebidae of Jordan were collected by fixed UV light traps from localities representing the main ecological zones of Jordan. The duration of the traps ranged from several weeks to more than 2 years for some locations. The traps were placed in Dibeen Nature Reserve (North Jordan), Al Shoumari Nature Reserve (Eastern Desert), Dana Nature Reserve (South Jordan). Traps were also placed in two University of Jordan farms in the Central Jordan Valley and one near Amman in the high lands. Some traps were placed in or near private farms or gardens. Specimens of Erebidae collected previously from Jordan and deposited in the University of Jordan Insect Museum (UJIM) were examined. As a result of this research, a large collection for the members of this family was established in the UJIM, which is the largest collection in the country so far. A total of 20 species in 12 genera were recorded from the different parts of Jordan. Catocala separata (Freyer, 1848) and Autophila ligaminosa (Eversmann, 1851) are new to Jordan. The data contributed to our knowledge of the spatial and temporal distribution of the Jordanian Erebidae. Available biological, ecological, distributional or zoogeographical data are given.
Elusive Parnassius mnemosyne (Linnaeus, 1758) larvae: habitat selection, sex determination and sex ratio (Lepidoptera: Papilionidae)
Authors: Vlasánek P. , Bartonová A. , Marec F. , Konvicka M.
Published: June 2024

The charismatic and regionally declining Parnassius mnemosyne (Linnaeus, 1758) is notable for surpluses of males in mark-recapture studies, as well as for poor detectability of its larvae, which develop on spring ephemeral plants, Corydalis spp. In order to study whether the bias towards male exists already in larval stage, we searched for the larvae at three localities in the Czech Republic and attempted to sex the larvae using two alternative methods: (i) by identification of the female specific sex chromatin formed by multiple copies of the W chromosome in polyploid somatic nuclei of the Malpighian tubule cells and (ii) by dissection of ovaries and testes. Finding the larvae in the field was extremely difficult, and 38 person-days of fieldwork yielded only 78 larvae. Consistent with the literature, they dwelled under sparse canopy of oak dominated mature woodlands or on woodland margins. Sexing by genitalia dissection worked well (N = 22) and revealed a prevalence of females (16 vs. 6). In contrast, the identification of sex chromatin was not possible as sex chromatin was absent (N = 56). Further cytogenetic analysis confirmed the haploid number of chromosomes n = 29, which is by one smaller than in the congeneric Parnassius apollo (Linnaeus, 1758). This reduction of chromosome number is probably the result of a fusion of sex chromosomes with a pair of autosomes, a situation not uncommon in Lepidoptera. The female-biased larval sex ratio, contrasting with male biases found so often in adults, is based on just 22 genitally dissected larvae, and may be biased by faster growth rate of males.

Few doubt that automation and artificial intelligence will change business and society in the future. Questions arise, however, regarding the motivations associated with such expensive corporation expenditures and the related ethics of the disruption and unemployment that may result from corporation development and installation of sophisticated technology. This study analyzes financial statement data of 100 large public corporations to understand those motivations and their consequences for corporation profitability and employees. The study results indicate that a more automated future may be profitable for corporations and their shareholders, but one of the costs of that future is significant disruption to employees. While some new positions may be created as a result of this technology, many employees will suffer disruption and will need extensive training to maintain employment in an evolving workplace. Many other employees will lose their jobs because the tasks that they once performed will be automated. The related ethics to business and society are profound.

The efficiency of perovskite solar cells (PSC) has increased from 3.8% to 25.5% since its first reported work by Miyasaka in 2009. These halide based perovskites have higher light absorption coefficient, charge carrier mobilities which results in increased efficiency. Therefore, as an alternate to the existing silicon based solar cells, perovskites are proven to be best in terms of efficiency than the other photovoltaic materials like dye sensitized solar cells, quantum dots based solar cells. Here, we have reviewed the ongoing developments in the domain of perovskite solar cells that have resulted in the higher efficiency. The focus of the review chapter is to put more emphasis on the working principle of the perovskite and the methods of increasing the efficiency and carrier lifetime of the metal halide perovskite structures. The importance of HTL and ETL materials have been discussed in detail as the efficient strategy to increase the charge carrier nature of the designed PVSC. We also focused on the research trends of this promising technology in terms of device modeling, cutting-edge methodologies, and innovative device topologies. Further we have discussed the challenges and prospects for PVSC research as a futuristic smart material in the renewable energy domain

This abstract presents a comprehensive overview of the AC-DC load flow solutions, a critical components and studies related to power systems for modern electrical grids. The integration of renewable energy sources (RES) and developments in transmission networks based on high voltages in the form of high-voltage direct current (HVDC) transmission systems have necessitated the development of advanced load flow techniques that can accurately model and results optimal power flows in hybrid AC-DC systems. AC-DC load flow analysis follows a numerical algorithm to calculate steady-state power flow across mixed AC and HVDC networks. Unlike traditional AC load flow, this method considers additional parameters, such as HVDC converter characteristics, control strategies, and interconnection constraints. By effectively incorporating these factors, the algorithm enables better representation of power flow dynamics and facilitates the integration of RES and large-scale HVDC transmission. The detailed representation of various components in AC and HVDC is crucial to capturing the system's behavior accurately. Special attention is given to HVDC converters, which can significantly impact power flow and controls line power flow and bus voltage. The abstract concludes by highlighting the importance of AC-DC load flow analysis in ensuring the reliable and secure operation of contemporary power systems. As renewable energy sources and HVDC transmission continue to gain prominence, understanding and implementing accurate load flow methods are essential for achieving a sustainable and resilient energy future

In India, Both urban and rural residents have had significant problems with the supply of energy. Energy is one of the major problems facing the globe today. Agribusiness waste and fuel wood provide 60–70% of the nation's energy needs. The sun radiates energy, which is a renewable resource with great potential. To replace the use of electric energy derived from petroleum, renewable energy is necessary. The utilisation of solar energy must be increased as it is now a source of renewable energy. Solar PV modules are typically employed in dusty environments, such those seen in tropical nations like India. Dust accumulates on the module's front surface, blocking incident sunlight.. It lowers the module's ability to generate electricity. If the module is not cleaned for a month, the power output might drop by up to 50%. The cleaning system, which was created, uses embedded code to clean the module. The power efficiency of the PV modules will be increased by cleaning off the dust

Biofuels are relevant from an economical, ecological, and social perspective since they are crucial in tackling a number of key worldwide concerns. Attention has been shifted from first generation feed stocks other types of feedstock to ensure food security to the world. Aquatic weeds have been difficult to contain in order to stop their global growth. They not only pose threat to environment and water bodies but also huge sums of money and labor must be diverted when they are removed from water systems in order to safely manage and dispose of the waste. The aquatic weeds have the potential to be both profitable and advantageous when utilized as a resource. In this work, we tried to explore the suitability of aqua weeds as feed stocks for production of bioethanol as to meet growing global demand for clean and safer energy. The suitability of aquatic weed as feed stock for bioethanol was addressed due to its high protein, carbohydrate, and fat content. We also discussed current challenges and process intensified techniques to convert this waste to a valuable product. Finally we concluded this topic with some insights into future scope of making these aquatic weeds as a regular feedstock for bioethanol production

The ongoing is the age of process intensification, wherein the best and most cost-efficient ways are chosen to revamp the conventional methods or equipments. Distillation is an age-old process but to make it run with modern day processes it has been modified in several ways, within the column as well as in the process. Here, in this research work, we have considered a three-feedmixture, commonly known as BTX system being separated in a partitioned wall column. The paper incorporates the modified and detailed design equations based on conventional multicomponent design equation FUGK, along with DWC design correlations given by Murlikrishna and Sotudeh with relevant changes to ease the steps involved in designing. The design module has been considered and is compared with conventional sequential columns for their techno-economic feasibility. Also, a modification is proposed for a more consistent middle product, which is usually an issue while running such columns and the same has also been accounted for energy calculations and economic benefits
