The reason why the roundhouse ball is banned in international competitionsIn the rules of table tennis, the server must throw the ball almost vertically upward with his hands without spinning the ball. This was one of the requirements for a legal serve. The ban on roundhouse shots in international competitions may be to ensure the fairness of the game, the rules, and the enjoyment of the game. The spinning of the roundhouse ball might destroy the balance set by the rules, making the competitive nature of the game develop in a direction that was not conducive to normal development. While watching the Olympics, you can also read the wonderful novels related to the Olympics!

Economics, financial engineering, and international economics and trade all sounded very similar. What was the difference between them?Economics, financial engineering, and international economics and trade are three different disciplines, although they may sometimes sound similar.
Economics is the study of human economic activities, focusing on how countries, companies, individuals, and organizations maximize their effectiveness while taking into account resource allocation and cost-effectiveness. The study of economics includes production, distribution, exchange, and consumption. Its goal is to reveal the essential laws of economic phenomena and provide decision-making support for the government and society.
Financial engineering is a field of applied mathematics, statistics, and computer science aimed at designing and implementing financial tools to help financial institutions and investors achieve their financial goals. Financial engineering usually involved the pricing, risk management, and investment optimization of financial instruments such as stocks, bonds, futures, options, and currencies.
International economy and trade referred to the economic activities of a country or region on a global scale, including trade, investment, logistics, and supply chain management. International economy and trade usually involved international trade rules, exchange rates, customs duties, immigration, and foreign policy.
Although there may be some similarities between economics, financial engineering, and international economics and trade, there are also many differences. For example, economics was more concerned with theoretical problems while financial engineering was more concerned with practical problems. International economy and trade also involved the cultural background, laws and regulations, and competitive landscape of different countries and regions.
The difference between cell engineering and fermentation engineeringMicrobiological cell engineering referred to the use of microorganisms for cell level research and production. The specific content included the cultivation of various microorganisms, the change of genetic traits, the direct use of microorganisms, and the acquisition of microorganisms 'cell metabolism products. For example, protoplasts fusion was used to modify the characteristics of microorganisms and create new varieties.
Fermenting engineering was a technical system that used the specific functions of microorganisms to produce useful substances through modern engineering techniques or directly applied to industrial production. In the fermentation process, it involved the separation and purification of the product. In the initial separation stage, methods such as precipitations and extraction were often used. In the further purification stage, liquid purification methods would be used. Moreover, the product of the fermentation process, whether it was the metabolism or the bacteria itself, needed to undergo quality inspection. Only after passing the inspection could it become an official product.
The main difference between the two was that the cell engineering of microorganisms focused on the research, transformation, and direct utilization of the cells at the level of microorganisms, while the fermentation engineering emphasized the use of the functions of microorganisms for industrial production, and focused on the subsequent production processes such as separation and purification of products and quality inspection.

slope engineeringSlope engineering was an engineering field that involved many aspects. There was a book titled "Slope Engineering" published by different publishing houses. The content of the book would focus on problems such as slopes, landslides, dangerous rocks, collapses, mudflows, and bank collapses. In combination with relevant national standards and specifications, it would elaborate on the investigation, testing, analysis, evaluation, treatment, and monitoring of slope engineering. It will introduce in detail various slope engineering analysis and evaluation methods and slope engineering treatment measures. It will also give several main application programs for slope engineering analysis and evaluation.
There are some problems in the classification rules of the safety level of slope engineering, such as unclear safety level, difficulty in classification, and intermittent changes. Although it is generally determined according to the relevant tables, the actual safety level is basically determined by the severity of the damage consequences (Level 1 when the damage consequences are very serious, Level 2 when it is serious, and Level 3 when it is not serious). There are contradictions between the current classification rules and the content of the table, and there is no corresponding relationship between the slope type and the severity of the engineering damage consequences, which will cause difficulties in the classification of the severity of the damage consequences and the safety level. There were relevant analysis and suggestions for these problems, such as adjusting the form of the safety level division table.
From the perspective of the Slope Engineering Technology Conference, the 16th Slope Engineering Technology Conference was held in Beijing on October 21st. The conference was themed with "Safety and Protection of Engineering Slopes under Extreme Conditions", covering the development status and future of modern slope engineering technology, survey and evaluation technology, prevention and control technology, safety intelligent monitoring and early warning technology, ecological restoration theory and technology, new construction methods, new technologies, new equipment, digital and intelligent technology, etc. This reflected the trend of slope engineering towards green, safe, digital and other high-quality development.
In terms of slope protection construction, the first step was to survey and set out, then set up a falsework, and then use a cannon machine to drill holes in the side slope (the position of the holes was required to be high, and the error of the hole distance was not more than 5 cm). After the acceptance was passed, an anchor rod made of several processed steel bars was placed, and then the cement mortar was poured into it. After the mortar solidified, the steel bar frame was built, and finally, the slope was afforested (using a grass spraying machine to scatter grass seeds). Through these layers of construction reinforcement, the firmness of the slope was guaranteed.
