Tomato is one of the main varieties in the global trade of vegetables and fruits. In recent years, the planting area of tomato has continued to expand. The simple and intensive planting combined with high temperature and wet environmental conditions has facilitated the growth and breeding of diseases and pests, which has led to a sharp decline in tomato production. In addition, excessive use of chemicals and fertilizers has led to environmental pollution, which has led to a decline in tomato quality, and has caused huge losses to China’s vegetable economy. In this experiment, the rhizosphere soil of several common tomato diseases was used as research materials, and ITS sequencing was carried out for rhizosphere soil fungi by using high-throughput sequencing analysis. The operational taxon units (OTUs), alpha diversity, beat diversity and community structure were analyzed.","PeriodicalId":110964,"journal":{"name":"Journal of Progress in Engineering and Physical Science","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122533334","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the importance of sustainable transition has been overlooked by many countries and large organisations. As climate change and energy scarcity become urgent, many large organisations are pursuing sustainable transformation to achieve low cost and resource reuse. A study of the existing literature reveals that the literature on the sustainable transformation of large organisations and multinational corporations is limited and not analysed more comprehensively. This paper aims to illustrate methods and recommendations for the sustainable transition of multinationals and to analyze the sustainable transition of multinationals using different theoretical factors and sustainability models. For example, the three pillars of sustainability, this section illustrates the operational and technological transformation of multinational companies; the 10 R’s of sustainability and value creation demonstrate the concepts that multinational companies focus on to meet their success criteria for sustainable transformation; and the importance of sustainable transition for multinational companies is also analyzed from the perspective of supply chain and corporate social responsibility. Meanwhile, links are made between these theories and models, indicating the importance of focusing on multiple dimensions for better accomplishing the sustainable transition.","PeriodicalId":110964,"journal":{"name":"Journal of Progress in Engineering and Physical Science","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136161852","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Gravitational energy regulates interactions in the universe: nuclear, chemical, electrical, and others. Each massive body generates a force gravitational field of attraction to it. Gravitational interaction spreads instantly. Masses or energy-carrying particles moving in gravitational fields emit gravitational waves. The signal from gravitational waves comes at about the same frequency as our inner speech. Gravitational waves carry information about energy, time and space. Humanity has long sought to overcome the power of gravity. If you shield the connection with the Earth’s core, then there will be an attraction to another field in the Sky. The article discusses ways to overcome gravity on earth and in outer space. The approach of cosmic levitation to interstellar galactic travel in the universe is also being considered. To levitate spacecraft, you need to use the setting on the fields of attraction. To levitate a spacecraft from Earth to the Universe, it is necessary to bring its energy to such activity that its ether contours will absorb the energy sphere of the target gravitational field. The reason for levitation and infinite energy lies in the ethereal shell, which needs a complex of vibrations of the field of attraction.","PeriodicalId":110964,"journal":{"name":"Journal of Progress in Engineering and Physical Science","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136161850","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The proposed method is transforming into a switched LQR problem by adopting linear transformation. Next, we adopt an embedding transformation method to convert the switched LQR problem to a traditional optimal control problem, so the bang-bang-type solution of the embedded optimal control problem in finite time is the optimal solution to the switched LQR problem. The switching sequence of modes and the switching instants can be calculated by solving a closed-form optimal switching condition. The optimal state feedback control law is determined simultaneously. Then, by solving a sequence of Riccati equation, we find some conditions that ensure switched LQR problem can be convert to the singular LQR problem. Finally, a numerical example is presented to demonstrate the effectiveness of the proposed method.","PeriodicalId":110964,"journal":{"name":"Journal of Progress in Engineering and Physical Science","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136161845","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We use various optimization prediction and optimization evaluation methods in this paper to determine the trends and causes of global temperature variation and make effective suggestions for them. We first constructed a first-order differential temperature model and found that the temperature rise in March 2022 was larger than that observed in the past 10 years. By constructing a prediction model (BP) based on BP neural network and a grey temperature prediction model (GAGM) optimized based on adaptive genetic algorithm, and by importing the data, we find that the average temperature in 2116 and 2145 will reach 20℃. In addition, if the correlation factor evaluation model (FAEM) is constructed in the country, and we conclude that there is a correlation between location, time and temperature. Next, we analyzed key environmental factors, such as volcanic eruptions, forest fires, and COVID-19. We imported the CO 2 concentration and temperature data into the FAEM evaluation model to obtain the results that natural disasters can lead to the temperature increase. Then nine environmental factors, including COND, NYKC, NYXH, GDP, PJRK, LJL, LZMJ, KJSP, and GJJY. Taking these factors as independent variables and temperature as the dependent variables, COND, NYXH, PJRK, LJMJ, JSL are the main causes of global temperature change and KJSP. This study provides an assessment of future global temperature changes, making recommendations for policymakers to optimize the energy mix and plant trees to effectively mitigate the global temperature rise.","PeriodicalId":110964,"journal":{"name":"Journal of Progress in Engineering and Physical Science","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136161843","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
