Submerged cultivation of medicinal mushrooms is receiving increasing attention and is considered an effective alternative to traditional substrate cultivation methods for producing fungal mycelial biomass and bioactive metabolites with diverse applications. This method allows for the control of culture environment conditions, enabling more efficient synthesis of bioactive compounds such as polysaccharides, triterpenoids, cordycepin, polyphenols, etc. Furthermore, the bioactivity of these compounds, including antioxidant, anticancer, antibacterial, and immunomodulatory effects, further emphasizes the potential of producing medicinal mushroom biomass by submerged cultivation in the pharmaceutical and functional food industries. Submerged cultivation is considered a promising alternative to traditional mushroom fruiting body cultivation because it offers better control over culture conditions and product quality, as well as shorter cultivation times. Submerged fungal cultivation has significant industrial potential; however, there are still challenges in optimizing production yield and scaling up the process for industrial application. The successful application of this method on a commercial scale depends on increasing product yield and developing new production systems to address the issues related to submerged mushroom cultivation techniques. Although many researchers are making efforts to produce bioactive metabolites from fungi, the physiological and technical aspects of submerged cultivation still require extensive and long-term research.
The laboratory can be seen as an environment where students can enhance their skills by transferring theoretical knowledge into practice. The purpose of this study is to evaluate the factors affecting the satisfaction of students and lecturers majoring in Chemistry, Biotechnology, and Food Technology from the Faculty of Technology and Sustainable Development at Thu Dau Mot University. A total of 300 students from freshman to seniors and their lecturer were surveyed using a questionnaire comprising 25 observed variables. The obtained information were subsequently analyzed using Exploratory Factor Analysis (EFA) and linear regression modeling. The results indicated that the proposed model consists of four independent factors (laboratory facilities, service competence, responsiveness, and school support) and one dependent factor (satisfaction), which demonstrated reliability with Cronbach’s Alpha coefficients greater than 0.6 and total variable correlation coefficients above 0.3. The EFA results of 19 accepted observed variables showed correlations among them, with a KMO value of 0.931, a Bartlett’s test significance of 0.000, and a total extracted variance of 70.435%. These 19 observed variables were grouped into four independent factors that correlated with the dependent factor (satisfaction with four observed variables), with sig = 0.000. The linear regression analysis confirmed the appropriateness of the model regarding the observed variables, with no signs of autocorrelation or multicollinearity. The factors influencing the satisfaction of student and lecturer with the laboratory were ranked, in order of importance, as follows: school support (β = 0.683), responsiveness (β = 0.130), and facilities (β = 0.129). All standardized residuals of the observed variables lay on a straight line, indicating that they followed a normal distribution.
MnO2 has the advantage of being environmentally friendly and abundant in soil, but its ability to activate persulfate is poor. This study combines MnO2 with CuO into a mixed metal oxide through a one-step reaction to increase the persulfate activation efficiency of the obtained product. These mixed oxides were synthesized by alkalization of a solution containing ions of two metals and then calcined at 300°C. The obtained oxide catalysts were characterized by methods such as FTIR, SEM, BET analysis, and zeta potential. The adsorption and decomposition of methyl orange (MO) were experimentally conducted in batch form using the above mixed metal oxides as adsorbents or persulfate activators. The results showed that the mixed oxides exhibited characteristic peaks in the FTIR spectrum, and were in the form of nanorods (CuO) and amorphous small particles (3:1CuO/MnO2). The CuO catalyst has a specific surface area of 20.23m²/g and pore sizes ranging from 20 to 30Å. The zeta potentials of both CuO and MO were highly negative, e.g., -46.5mV and -24.1mV, respectively. The adsorption capacities of MO onto the mixed oxides were quite low (~13.5%) and decreased gradually as the CuO content decreased. However, the persulfate activation capacity of the mixed oxides for MO decomposition was quite high, e.g., that of 3:1CuO/MnO2 for 40mg/L MO was 74.1%. In addition, the decomposition of MO almost followed pseudo-second-order reaction kinetics.
The manuscript contends that the strengthening of Australia's diplomatic relations with Southeast Asia can be attributed to the escalating threat posed by China's rise, the US's precarious role in the Asia-Pacific landscape, and the increasingly complex economic interconnections between the US, Australia, and Southeast Asia vis-à-vis China. Historically, the strategic alliance with the United States has been the cornerstone of Canberra's foreign policy framework. Nonetheless, Canberra's concerns about Washington's uncertain presence have grown as a result of the ongoing changes in US National Security Policy over the previous decade, from 2016 to 2025. In the long run, it can be argued that the dominant trajectory indicates Canberra's intention to strengthen its comprehensive strategic partnership with Southeast Asia, despite the increased complexity and fragmentation observed within Australia's multicultural society. While some analysts argue that Canberra's strategic alliance with the United States still predisposes it to prioritize the abandonment of Southeast Asia, there is a counterargument that Australia's strategic partnership with Washington is gradually dwindling after over 75 years of establishment and evolution. In light of the aforementioned circumstances, the manuscript advocates for Australia to recalibrate its domestic policies, particularly its ethnic policies concerning the Asian immigrant populace, and to leverage the existing networks of economic and social relationships with Southeast Asian nations, thus cultivating a framework of alliances among middle powers within the region, which would mitigate the risk of becoming ensnared in the strategic rivalry between the US and China in Southeast Asia.
The callus is a disorganized mass of cells that grow in plants in response to various biotic and abiotic stimuli. Callus plays an important role in cell cultures in vitro, as a starting material for many subsequent studies such as single-cell culture, protoplast culture, micropropagation, etc. In this review, callus as well as the factors affecting callus formation and proliferation (plant growth regulator, mineral medium, carbon source, type of explant, light condition, callus line) are explored to provide a brief overview of callus culture
In electronic circuits that use various integrated circuits (ICs), ICs may malfunction while assembled, used, and repaired. There are numerous ways to verify that ICs are operating, such as by measuring basic current and voltage with a VOM meter. However, many sophisticated operations are hard to measure and test, and the accuracy of the tests is low and takes a long time. Thus, it is crucial to have a tool that can rapidly determine whether or not integrated circuits are operating correctly. The purpose of this article is to develop a tool for testing the functionality of logic gate ICs. By modeling its properties using the truth table of the specific IC, the device employs an Arduino to verify the condition of the gates in a logic gate IC. After successful simulation and testing, they are assembled to form a final device.

Rich in bioactive compounds like mangiferin, flavonoids, phenolic acids, and terpenoids, mango leaves exhibit antioxidant, anti-inflammatory, anti-diabetic, antihypertensive, antimicrobial, gastroprotective hepatoprotective, neuroprotective and other bioactivities. These activities are linked to their ability to neutralize free radicals, modulate signaling pathways, and inhibit pathogenic microorganisms. Mango leaf extracts show promise in managing metabolic disorders, skin conditions, and age-related damage. Despite promising preclinical results, further clinical studies are needed to validate their therapeutic potential and safety in humans.
This research is conducted as a test of the level of satisfaction of residents in the Central Highlands of Vietnam, specifically in DamB’ri Commune, Bao Loc City, Lam Dong Province. The survey of 100 residents at 4 hamlets of DamB’ri Commune did not record statistically significant differences in the level of satisfaction of participants for the criteria including sexes, educational level, occupation, and working age. Nevertheless, there was a statistically noticeable higher level of satisfaction with Health Insurance for participants who are officers at Hamlet 3. The results of the multiple linear regression method, including 7 independent variables and 1 dependent variable, based on the Health Belief Model (HBM), show that the awareness about restrictions and benefits are the core factors impacting the level of satisfaction of residents. The results also provide crucial evidence for authorities and policymakers to devise plans and solutions to increase the level of satisfaction with Health Insurance for people in Central Highlands.

However, challenges remain with moderate ease of use (M = 3.92), low confidence in AI tools (M = 3.68), and limited institutional support (M = 3.45). Qualitative insights indicate a need for systematic training and collaborative environments. The findings emphasize that successful AI adoption relies on institutional investment in training and infrastructure. Without this support, the gap between enthusiasm and actual implementation may hinder AI's transformative potential. Policymakers and educational leaders need to create structured frameworks for effective AI integration in EFL classrooms.
THE Impact Ranking reflects the impact and contribution of universities around the world, including Vietnam, to the community towards the 17 sustainable development goals of the United Nations. The purpose of this study is to evaluate the ranking results of Vietnamese universities in this ranking and the sustainable development goals that they are pursuing. The results show that from only one Vietnamese university among 467 global universities ranked in 2019, there are now 13 Vietnamese universities out of 1,936 global universities in the rankings. In addition to the mandatory SDG17, most Vietnamese universities mainly focus on the 8 SDGs related to economy, health, education, peace, equality and community (SDG1, SDG3, SDG4, SDG5, SDG8, SDG10, SDG11, SDG16). However, few universities focus on the goals related to poverty and environmental resources (SDG2, SDG6, SDG7, SDG9, SDG12, SDG13, SDG14, SDG15). This situation poses great responsibility and challenge for Vietnamese universities in accompanying the world in realizing the goal of sustainable development. This study is a reference resource for Vietnamese universities to identify sustainable development goals that should be prioritized in their short-term and long-term plans when participating in THE Impact rankings, in order to contribute to building a peaceful, just and prosperous society
The theory of differential equations arises from the study of physical phenomena. This field has various applications in science and engineering. The study of qualitative properties for each mathematical model plays an important role, attracting the attention of both theoretical and applied researchers. Normally, the most significant qualitative property to be studied first is the existence and uniqueness of the solutions of each mathematical model. However, proving existence and uniqueness results for mathematical models where the source function has a singularity is a difficult problem and requires many different techniques. In this paper, we establish some new conditions suitable to achieve the unique solution criterion for ordinary first-order differential equations. To obtain the desired results, we have improved the methods that have been used to prove the results in the work of Krasnosel'skii and Krein (Krasnoselskii and Krein, 1956). In addition, we also provide an example to illustrate the theoretical results.
Full-duplex non-orthogonal multiple access wireless networks with energy harvesting have the potential to improve spectral efficiency and save energy. However, wireless signals are susceptible to eavesdropping by other devices within their coverage area. This paper studies the security performance of a full-duplex non-orthogonal multiple access wireless network with energy harvesting (FDNOMAWNwEH) over Nakagami-m fading channels. Results show that the total throughput increases as the power of the primary transmitter increases. Similarly, the total throughput also increases as the expected security level or the energy harvester efficiency increases. In addition, there exists a value of the NOMA power division factor that maximizes the total throughput. Furthermore, the results show that the total throughput decreases as the fading severity parameter increases.

Effectively carrying out this work ensures equality, solidarity, and shared development among ethnic groups across the nation. This article evaluates the current status of ethnic affairs and the Khmer ethnic cadre force in Tra Vinh province and proposes several solutions to enhance ethnic work and develop a contingent of ethnic cadres capable of meeting the demands of the new era.
Traditional education in Southern Vietnam developed through two main periods: the era of the Nguyen Lords (1698-1802) and the reign of the Nguyen emperors (1802-1862). This article focuses on education development in Southern Vietnam during the reign of the Nguyen emperors. Despite the numerous difficulties experienced during the decline of the feudal regime, the Nguyen emperors made significant efforts to promote education in the South. The royal court showed commitment, introduced reforms, and created favorable conditions for educational activities to thrive, resulting in greater academic success compared to the previous period. Alongside civil service examinations, the establishment of public schools and supporting educational institutions was also actively promoted. The institutionalization of state-led educational activities inherited the achievements of the earlier period and marked the consolidation of educational functions during a historical development phase
The study investigates the challenges faced by Food Technology students at Thu Dau Mot University in mastering English reading and writing skills. The findings reveal that limited vocabulary and grammar knowledge significantly hinder students' proficiency in these areas. For reading, students struggle with insufficient vocabulary, poor comprehension strategies, and a lack of background knowledge, making it difficult to understand texts, identify main ideas, and interpret references. Similarly, writing is affected by challenges such as improper grammar usage, insufficient vocabulary, awkward phrasing, and issues with sentence construction. Mistakes in punctuation, spelling, and word order further reduce the quality of written work, limiting students’ ability to express ideas clearly and cohesively. These difficulties stem from a combination of linguistic limitations, lack of exposure to English, and insufficient support in structured learning strategies. The study highlights the urgent need for targeted interventions to address these challenges. Proposed solutions include vocabulary enhancement exercises, grammar-focused sessions, structured reading techniques, and writing workshops. Additionally, integrating modern tools like AI-powered learning applications can provide personalized feedback and improve overall proficiency. By adopting these strategies, students can gradually overcome their difficulties, enhancing their reading and writing skills to meet both academic and professional demands. The findings emphasize the importance of consistent practice and tailored learning approaches in language development.
This article examines the role of social networks and informal institutions in facilitating the resettlement and socio-economic integration of Vietnamese returnees from Cambodia in the Tri An Lake region, Dong Nai Province. In the context of statelessness and the absence of legal identification, these returnees faced significant barriers in accessing official support from local authorities. Under such circumstances, kinship-based networks, fellow migrant connections, and local community ties—together with informal support mechanisms —played a pivotal role in providing essential resources such as shelter, livelihood opportunities, informal credit, and emotional support. Drawing on oral history interviews with Vietnamese returnees who have resettled around Tri An Lake since the late 1980s, the study reveals that these social connections and informal institutions helped individuals navigate initial crises and contributed significantly to their long-term stability and integration.
