Calculation capacity is one of the specific competencies that need to be developed for students, formed mainly in teaching Mathematics and other subjects, including Chemistry. The development of calculation capacity can be accomplished by different methods. One of the effective measures is using exercises in teaching chemistry. In this paper, a procedure for constructing and application of the exercise “Sulfur and sulfur compounds” in order to develop calculation capacity for high school students will be presented.

The reversible thinking is the way of thinking in two opposite directions, which then support each other to help people perceive and solve problems flexibly and effectively. In this article, we mention manifestations of students' reversible thinking competence in teaching functions and graphs and propose measures to foster this ability in order to contribute to improving the quality of teaching mathematics at high schools.

From 1986 to present, Vietnamese novels have had many changes, artists have faced many opportunities and challenges. They have kept searching and innovating to keep pace with the times and meet the needs of the readers. Following the writer's creative journey, the novels have proved not only the unity and inheritance but also their own unique features. That diversity is partly due to the fact that the writers have constantly searched for new ways of generalizing reality. Among them, the method of mythization has created a multi-faceted, multidimensional view of the world. So how does the method of mythization contribute to discovering the realistic essence of Vietnamese novels from 1986 to the present? That's the question this article addresses.

The current study was carried out to assess the antioxidant expression of the seed’s black-testa peanut cultivar namely CNC1 in the artifical drought condition. The oxidative stress with a burst of O2 .- and H2O2 in peanut leaves resulted the obviously cellular membrane damage that was illustrated by an increase of lipid peroxidation. A high induced activity of enzymatic antioxidants such as SOD, CAT and POX would detoxify the excess of O2 .- and H2O2. An increase in content of amino acid proline protects the stressed cells by adjusting intercellular osmotic potential. The antioxidative expression of CNC1 plants was similar to that in L20 cutivar - a drought tolerant cutivar of peanut.

The birth of the theory of socio-economic forms of Marxism - Leninism has created a revolution in the perception of the process of movement and development of the history of human society. The reactionary forces are finding many ways to attack and distort the content of this theory. Prominently,they give other social theories to negate the revolutionary and scientific value of the theory of socio-economic models, distorting the interpretation of Marxism - Leninism on the historical - natural nature of the development of socio-economic models; reconsidering the issue of inevitability to pass through the social revolution to move forwards from capitalism to socialism; taking advantage of the dissolution of the Soviet Union and the socialist countries in Eastern Europe to deny the empirical value of the theory of socio-economic forms. Identifying and pointing out these wrongful views is very important to protect the scientific, revolutionary, and empirical value of the theory, and contribute to the creative application of Marxism-Leninism in the implementation of the tasks of our country's revolution today.

The Max-Cover is a NP-hard problem. Therefore, the heuristic approach is suitable to solve this problem for large instances. Quantum annealing is a heuristic quantum optimization algorithm that can be used to handle the Max-Cover problem. Recent developments in quantum technology allows creating programmable quantum processors to implement the quantum annealing technique. In this article, we apply the quantum annealing approach to solve the Max-Cover problem. The experimental results show that this approach gives better results than Simulated Annealing in terms of both solution quality and annealing time.

Currently, the design and organization of project-based teaching is a practical matter, which has been widely applied to help learners acquire the necessary knowledge and skills to apply to specific and practical issues. In project-base teaching, theoretical knowledge is intergrated into practice to help learners practice how to apply theoretical knowledge to real life topics and situations. That will help students grasp the practical meaning of knowledge, and step by step understand how to apply it in practice and solve real-life problems. One of the current urgent problems that need to be researched and solved is the problem of environmental pollution caused by climate change. Therefore, in this study, environmental issues are integrated into the curriculum, the research topic is the solar cell project taught in the form of a project-based at high schools. From the results of experimental pedagogical research, the effectiveness of teaching solar cell-theme projects at some high schools is evaluated.

In the field of image processing, image recognition is one of the major challenges for researchers in recent years. The goal of recognition is to detect and extract features in the images to classify samples into different layers. One problem of great interest in this field is self-driving robot cars using image processing. The aim of this research is to present a deep learning method to solve the path recognition matter for robots. A self-driving robot model will be built based on the convolutional neural network with the use of different layers to automatically extract the best features in the image. Experimentation procedure has been carried out and results with low error rates had been obtained
