subjects in many countries and the treatment of breeding waste has to be taken as a priority. Nowadays, biogas technology sets up and operates primarily to treat breeding waste. However, this technology formed a considerable amount of wastewater the effluent quality is still poor and the concentration of pollutants is higher than the required national technical regulation (QCVN 40:2021/BTNMT). Thus, the project aimed to find out an appropriate procedure to reduce environmental pollution from breeding wastewater of the biogas system which then can be applied in the constructed wetlands system. Two units of Horizontal Flow Constructed Wetland (HFCW) and Vertical Flow Constructed Wetland (VFCW) were located and set up in two treatments with three replications. Both of these units were planted with Cyperus involucratus. Wastewater was fed into the wetland units at a mean flow rate of 312 ml/day. Major parameters including COD, BOD5, SS, N-NH3; P-PO43- were measured. The results indicated that vertically Flow Constructed Wetlands exhibited a higher treatment efficiency than horizontally Flow Constructed Wetlands with the average removal efficiency for COD, BOD, SS, N-NH3, and P-PO43- were 55.2 %, 75.3 %, 82.3 %, 75.9 %, and 70.1 %, respectively. Generally, the study demonstrated that the constructed wetlands can be used as an option for improving the quality of biogas wastewater.

The issue of marine pollution in general, as well as pollution brought on by oil spills into the sea, in rivers and lakes, or wastewater from factories, businesses, mechanical repair shops, gas stations, universities, and auto repair shops, is one that the world is currently facing, particularly since when it does, it invariably results in harm to the environment and people. Oil spills result in oil plaques on the ground, in rock crevices, washed up on the coast, a foul smell, a loss of tourism beauty, harm to the ocean's ecosystem, and even equipment damage. equipment, supplies, water transportation, etc. We had to use very expensive oil spill blotting papers at the time. The amount of hair that individuals discard each day is not little, and even when it is burned, it emits unpleasant scents and polluting gases that are harmful to human health. Furthermore, it is very easy to make a hair mat at vehicle wash facilities, school restaurants with big parking lots, and car repair shops. To prevent the majority of the oil from being spilled into the environment, handmade oil-absorbing carpets made of hair materials are laid over the drains in these locations.

Vietnam's economy is operated to serve more than ninety million people so this is a very vivid picture. The large population brings many advantages to the food production sector in general and the production of fresh noodles in particular. Fresh vermicelli is the raw material for processing many dishes of the Vietnamese people for a long time, that's why there are many Vietnamese dishes with indispensable ingredients, which as Noodles in the national culinary books. Vietnam. The production of fresh vermicelli with the main ingredient is fermented and shaped rice with simple steps, but hidden inside there are environmental issues that need to be considered. The production and business associated with environmental protection are the responsibility of most enterprises and production facilities in Vietnam. The fresh noodle food production industry is no exception. Instead of learning about the aspects that affect the environment in the traditional way of collecting information, analyzing, and evaluating the current situation, this time the research team looked at understanding the causes of environmental pollution in terms of consumption. ISO 14001 international standard. ISO 14001 Environmental Management System is an international standard that helps businesses and establishments identify the important role of the environment as well as the risks brought by the environment, thereby realizing the environment as an activity of the Organization. In this standard, the commitment to prevent environmental pollution is a mandatory condition, so determining the environmental aspects to overcome the impacts is a key element of the standard. If a business achieves ISO 14001 Certification, it will have a very good effect in promoting the corporate image of being responsible for the environment and the community.

Heavy metals are the most dangerous substances in the environment, have caused deleterious effect not only to the environment but also to the public’s health. Different studies have demonstrated that plants have a high removal capacity for lead ions from pollution sources. However, these plant species were rather limited. Thus, the project aimed to find out plant species that represent its lead removal ability to reduce environmental pollution. The experiment was carried out factorially as a randomized complete design in hydroponic systems with four treatments (0, 100, 200, and 300 mg/l of Pb) and three replications. The results indicated that the growth of the Dracaena sanderiana plant is well in Pb concentration of 100 mg/l, with less growth while the increasing lead concentration of 200 mg/l and 300 mg/l. The amount of lead in the water of three treatments 100 mg/l, 200 mg/l, and 300 mg/l after 30 days of the experiment decreased by 91.5%, 86.8%, and 86.4%, respectively. It was found that Dracaena sanderiana exhibited high lead treatment efficiency in the water. Moreover, results showed that the accumulation of lead in the roots of Dracaena sanderiana is quite large with treatments of 100 mg/l, 200 mg/l, and 300 mg/l lead concentrations were 5073.8 mg/kg, 5134.0 mg/kg, 7054.0 mg/kg, respectively. In contrast, the ability to lead accumulation in plant leaves and stems is lower. cultivated in hydroponic systems with four treatments and three replications. Four levels of Pb(NO3)2 (0, 100, 200, and 300 ppm) were used. The monitoring indicators include the contents of lead in water, the growth target of Dracaena sanderiana, and the accumulation of lead contents in different organs of Dracaena sanderiana. The results indicated that: the growth of the Dracaena sanderiana plant is well in Pb concentration of 100 ppm, with less growth while the increasing lead concentration of 200 ppm and 300 ppm. The amount of lead in the water of three treatments 100 ppm, 200 ppm, and 300 ppm after 30 days of the experiment decreased by 91.5%, 86.8%, and 86.4%, respectively. It was found that Dracaena sanderiana exhibited high lead treatment efficiency in the water. Moreover, results show that the accumulation of lead in the roots of Dracaena sanderiana is quite large with treatments of 100 ppm, 200 ppm, and 300 ppm lead concentrations were 5073.8 mg/kg, 5134.0 mg/kg, 7054.0 mg/kg, respectively. In contrast, the ability to lead accumulation in plant leaves and stems is much lower.

ABSTRACT This paper analyzes the security performance of underlay cognitive energy-harvesting relay radio networks (UCEHRRN) through the Monter-Carlo simulation results. The results clarify the influence of critical operating parameters on the security performance of the system. Furthermore, the security capabilities of UCEHRRN have been compared with those of the live transmission system. Moreover, many results show that the security performance of the system is significantly improved. Analysis of the results also shows that UCEHRRN is especially effective when the direct transmission system cannot achieve security due to objective reasons such as path loss, severe fading, and shadowing.

As a response to global warming and climate change, climate change adaptation aims to lessen the susceptibility of social and biological systems to relatively abrupt change and so counteract the effects of global warming. Openness and cooperation are key tenets of an adaptation strategy; as a result, mechanisms for a wide range of stakeholders are included in the creation and execution of adaptation strategies. However, few poor nations have made a point of involving stakeholders in decision-making processes for climate change adaptation. In many regions of the world, there is a notable dearth of concrete plans to include stakeholders in the adaptation of policy-making and implementation. This study uses Viet Nam as a case study to evaluate the level of stakeholder involvement in climate change adaptation strategies. The findings demonstrate that the Vietnamese government has adopted a "top-down" decision-making strategy, in which the government plays the primary role, communities and NGOs have a minimal impact on the creation and implementation of policies, and the private sector is only involved in the implementation phase. Stakeholder participation has generally been acknowledged in Vietnam, although the country's national climate change policies have not been adequately implemented. As a result, the policies for adaptation are unlikely to be effective in the unique settings of diverse places and may not be embraced by all stakeholders, which may ultimately limit adaptation activities. Viet Nam is advised to encourage participation by many stakeholders in the formulation of policy. Other countries can adopt the lessons from Vietnam while creating their adaptation policies.

In this study, we examine students at Thu Dau Mot University specializing in Food Technology’s speaking and listening skills in English. We conducted a survey on 59 students majoring in Food Technology using the questionnaire approach. Students struggle to develop macro-English abilities like speaking and listening, as seen by their responses. mastering English grammar, vocabulary, and other micro-skills might be challenging. The findings indicate that significant obstacles to learning listening and speaking skills include a lousy sound system, a lack of a communicative context, a limited vocabulary, a lack of cultural understanding, and a fear of making mistakes in communication. The findings also demonstrate that students’ limited exposure to English and weak phonological skills are to blame for their difficulty acquiring pronunciation. Many words are long and complicated, making learning and recalling word parts like verbs, nouns, and adjectives challenging. Many words are also difficult to pronounce. Learning the grammar of verbs and articles is challenging for students. When the challenges are solved, this research aims to effective foreign language learning.

In this paper, we consider the Robin-Dirichlet problem for a system of nonlinear pseudoparabolic equations with viscoelastic term. By the Faedo-Galerkin method, we first prove the existence and uniqueness of solution for the problem. Next, we give a sufficient condition to get the global existence and decay of the weak solution. Finally, by the concavity method, we prove the blow-up result of the solution when the initial energy is negative. Furthermore, we establish here the lifespan of the solution by finding the upper bound and the lower bound for the blow-up time.

In this paper, the Neumann-Dirichlet boundary problem for a system of nonlinear viscoelastic equations of Kirchhoff type with Balakrishnan-Taylor term is considered. At first, a local existence is established by the linear approximation together with the Faedo- Galerkin method. Then, by establishing several reasonable conditions and suitable energy inequalities, the solution of the problem admits a general decay in time.

In this study, the author researches the numerical results of the comparison of synchronization speed of regular neural networks with unidirectional and bidirectional coupling. Each neuron is linearly coupled with the others and is represented by a reaction-diffusion system of FitzHugh-Nagumo type. The result shows that the necessary coupling strength for the synchronization in two cases decreases when the coupling number of neurons increases. In other words, the bigger the coupling number of neurons in the regular networks is, the easier the synchronization occurs. Moreover, synchronizing the regular networks with bidirectional coupling is easier than the one with unidirectional coupling over the same given number of neurons.
