Abstract
Computational thinking is an analytical idea and an important educational idea. Discrete mathematics is a compulsory course for computer science majors, which contains a lot of abstract thinking in the content of the course, and plays an important role in the development of students' logical thinking ability and comprehensive quality and so on. This paper mainly analyses the problems existing in the teaching of discrete mathematics from the perspective of practical teaching, and discusses how to intersperse computational thinking in the teaching process of discrete mathematics through the clever setting of cases.

Abstract
Based on the climatic conditions of the seasonal freezing area, the study of basalt fi ber and high viscosity modifier on the performance of the drainage asphalt was conducted to i mprove the disease of the drainage asphalt pavement. On the basis of SBS asphalt, 16 groups of composite modified asphalt blending schemes were designed for two modified materials, and multi-index tests were carried out under different blending ratios, and 16 groups of composite modified asphalt were tested with three indexes and Brinell viscosity. It is concluded that the performance of composite modified asphalt is the best when the yield of basalt fiber is 1% a nd the high viscosity modifier is 4%.

Abstract
Tomato is one of the most consumed fruits in the world due to its nutritional richness and its role in the agro-food industry, giving rise to a wide range of derived products. However, its production in Lubumbashi is constrained by several factors, particularly the infertility of the soils in this region. Among the solutions proposed by researchers to address this issue, organic fertilization stands out due to its capacity to restore and improve soil properties and fertility. Consequently, farmers resort to exogenous fertilization without knowing the origin and method of application that could allow for the rational use of fertilizers. It is in this context that this study was initiated with the objective of evaluating the influence of the origin of organic fertilizers and the method of application on tomato behavior. To this end, an experiment was conducted in the experimental field of the Faculty of Agricultural Sciences following a factorial design (3x2) with four repetitions. The observations during this study focused on growth and production parameters. The collected data were subjected to two-factor analysis of variance at a 5% significance level using R software, and Tukey's test was applied in case of significant differences. The results indicate that significant differences were obtained for all parameters except for the survival rate. In terms of plant height under the effects of the application methods, the treatment with 30 t/ha of localized chicken manure produced the tallest plants, estimated at 26.125 ± 2.947 cm, compared to the shortest with the broadcast treatment of 30 t/ha of manure, evaluated at 13.250 ± 2.435. Neither the interactions nor the sources of manure induced significant differences. For the collar diameter of the plants, only the methods of applying fertilizers induced significant differences.
Regarding interactions, the treatment with 30 t/ha of chicken manure from the Congo Egg farm localized yielded a production estimated at 36.08 ± 4.17 t/ha compared to the lower yield obtained from 30 t/ha of manure from the Hasna farm by broadcasting, estimated at 27.08 ± 1.38 t/ha.

Abstract
Rhazya stricta is a perennial shrub of the Apocynaceae family, thriving in arid and semi-arid regions of South Asia, the Middle East, and North Africa. This plant has been widely recognized for its medicinal properties in traditional systems of medicine, such as treating diabetes, hypertension, gastrointestinal disorders, and skin ailments. The bioactivity of R. stricta is attributed to its rich phytochemical composition, including alkaloids, flavonoids, tannins, and terpenoids. Among these, indole alkaloids are particularly notable for their diverse pharmacological effects. Modern research confirms the plant’s antioxidant, anti-inflammatory, antimicrobial, anticancer, and antidiabetic properties. These findings provide a scientific basis for its traditional uses and highlight its potential in the development of novel therapeutic agents. However, challenges such as potential toxicity, sustainable harvesting practices, and a lack of extensive clinical validation remain barriers to its broader application in contemporary medicine. This report explores the botany, phytochemical constituents, and medicinal applications of R. stricta. It emphasizes the need for sustainable utilization, advanced phytochemical studies, and clinical trials to fully harness its therapeutic potential while addressing ecological and safety concerns.
