Authors: Yao Pei , Cremilda Samuel Jofrisse 
Published: July 2021

Abstract
China is a large agricultural country, shouldering the heavy responsibility of agricultural production, facing great pressure and challenges under the influence of geological disasters. Frequent agricultural geological disasters have a serious impact on people’s agricultural production and life. The complex geological structure of agricultural production areas, especially the wide distribution and large number of regional fault structures, especially the lack of popularization of geological disaster knowledge among rural residents, is also an important cause of geological disasters. Fault interpretation is the core of complex structure interpretation. The efficiency and degree of interpretation directly affect the progress of agroecological hazard risk assessment.

Abstract
Recent events have shown that there are big loopholes in the global food system. In order to analyze the pros and cons of the existing model, we have analyzed the evaluation and construction of the food system according to the following logical thinking to highlight the sustainability and fairness of the food security system. Firstly, this thesis uses the Entropy Weighting Method to evaluate, compare and analyze food security in each country, for the convenience of the model, we randomly sampled the top 73 countries in the world’s comprehensive strength rankings and selected 33 samples. According to the four goals we are going to discuss: efficiency, profitability, sustainability, and fairness. 14 specific secondary indicators are selected. Combined with the DEA model, we further scored the preliminary model. Secondly, we select the United States and China as representatives and bring them into the model for calculation. It is found that the improvement of the model makes developed countries no longer have an advantage in comprehensive scores. It can also indicate that in the current food system, developed countries are more concerned about efficiency and profitability, which to some extent leads to weaker sustainability and fairness.

Authors: pei-han WU , Hui Long Lin 
Published: July 2021

Abstract
Dingxi City of Gansu Province is a typical ecological fragile area and a famous poverty-stricken city in China. Because of its harsh natural environment and traditional farming ideas, economic development there has been slow. With the implementation of “Agricultural Supply-side Reform” in China, some regions have developed grassland agricultural production mode (GAPM) by introducing grass into fields, but there are still many regions that conform to traditional cultivated land agricultural production mode (CLAPM). In order to find out the suitable agricultural production mode for Dingxi City, two production modes, GAPM and CLAPM there were studied. This study used opportunity cost method and alternative engineering method to compare the ecological benefits of the two production modes. The results showed that the values of GAPM to provide products, conserve soil, regulate climate, sequestrate carbon and product oxygen were 479.31 yuan / mu,483.51 yuan / mu,1.94 yuan / mu,394.6 yuan / mu, and 393 yuan / mu respectively, better than CLAPM. Therefore, GAPM in Dingxi City has been effective, indicating a new suitable industrial mode for Dingxi city and other regions with the same requirement of agricultural industry updating.

Published: July 2021

Abstract
The complex agricultural supply chains make it difficult to validate whether agricultural products meet the quality standards. In the supply chain of agricultural products, traceability system is an effective means to ensure the quality and safety of agricultural products. In this study, an easy-to-use simplified traceability system of agricultural products (STSAP) for small and medium-sized enterprises was constructed based on Android. The proposed STSAP provided a high level of traceability and had the characteristics of friendly interfaces, simple operation, and automatic generation of traceability files. STSAP consisted of six functional modules: account management, site management, planting materials management, agricultural activity management, processing management, and traceability files management. These modules recorded soil fertility, crop growth stages, fertilization, irrigation, and pesticide application. Thus, this study helps farmers improve agricultural production and helps consumers trace production processes and transaction records.
Fine-Grained Image Classification on Agricultural Pest Larvae
Authors: Cheng Zekai , Xia Wan 
Published: July 2021

AbstractPest management is an essential part of the growth of crops. Accurately identifying the types of pests in the early stage is conducive to formulating targeted prevention and control measures to reduce pests’ impact on grain production. In order to identify the pests in the larval stage as early as possible, in this paper, we compare the conventional classification model and the fine-grained classification model and construct a fine-grained image classification model that can be used to classify the larvae of crop pests, which improves the ability to identify pests in the larval stage. Experiments show that our optimized fine-grained classification model surpasses the general convolution image classification model on the fine-grained agricultural pest datasetAgrFIP20.

Published: July 2021

Abstract
Polybrominated biphenyls (PBBs) are a class of industrial chemicals with the characteristics of persistent organic pollutant, which can cause pathological effects on the endocrine system such as the thyroid and adrenal glands. At the present study, the experiment was designed to obtain the effects of PBB153 on the levels of E2, T and Vtg in zebrafish. The zebrafish were exposed to increasing concentrations of PBB153 solution (0, 0.1 mg/L, 0.2 mg/L, 0.5 mg/L) for 21 days. The results showed that PBB153 had a certain inhibitory effect on the secretion of E2, T and Vtg in zebrafish. However, there are relatively few studies on the harm of PBBs and others environmental chemical pollutants to the endocrine system of aquatic organisms, and further research is needed.

Abstract
[Objective] To determine the effect of microbial fertilizer combined with compound fertilizer on the chemical composition content of flue-cured tobacco leaves. [Method] Before planting the flue-cured tobacco, the local conventional fertilizer varieties and microbial fertilizer were applied to tobacco pond annular hole according to the conventional dosage. The experiment has four groups with different treatments, namely T1: without any fertilization; T2: 4 kg of pure nitrogen per mu, applying humic acid organic-inorganic compound fertilizer with 50 g/plant when planting tobacco; T3: reducing the total amount of conventional fertilization by 50%, and applying 80 g/plant of microbial fertilizer; T4: applying only 80 g/plant of microbial fertilizer. The trial adopted a randomized block design, with 3 replicates for each treatment. After the tobacco leaves were harvested and cured at the maturity stage, 5 kg of the lower (X2F), middle (C3F) and upper (B2F) first-cured samples were taken for chemical composition determination and analysis. [Results] The results show that T3 treatment can effectively increase the total sugar, reducing sugar, total nitrogen, nicotine, potassium, and chlorine content in X2F, C3F, and B2F grade tobacco leaves, which ratios are between 20.10% ∼ 21.03% and 18.90% ∼ 19.90%, 2.68% ∼ 3.26%, 2.28% ∼ 3.15%, 2.21% ∼ 2.50%, 0.56% ∼ 0.72%, meeting the production standards of high-quality tobacco. Secondly, T4 treatment can significantly improve the sugar-alkali ratio, nitrogen-alkali ratio, and potassium-chloride ratio of X2F grade tobacco leaves, and it can improve the sugar-nitrogen ratio of C3F and B2F grade tobacco leaves, but the effect is not significant; T3 treatment has a significant effect on B2F grade tobacco. The nitrogen-nitrogen ratio of tobacco leaves has a significant effect on improving the sugar-nine ratio, potassium-chloride ratio and the sugar-nitrogen ratio of X2F ∼ B2F grade tobacco leaves, but the effect has not reached a significant level. [Conclusion] Microbial fertilizer combined with compound fertilizer can improve the content of chemical components in flue-cured tobacco. On the whole, the application effect of T3 treatment is better, that is, the application effect of 80 g/plant microbial fertilizer and 50% reduction of conventional chemical fertilizer is more ideal.

Published: July 2021

Abstract
The use of high quality equipment in the construction of asphalt pavements is one of the ways to get financial profit from the further use of the developed roadbed. Taking into account the peculiarities of delivery of asphalt mixture to the object of construction, its storage, moving into the hopper of the paver, can significantly reduce the phenomenon of segregation of the mixture, both fractional and temperature. Attention paid to the process of surface formation by the paver, docking with arriving dump trucks, prevents the appearance of defects in the laid layer: joints, potholes, irregularities. The analysis of negative phenomena that may arise in the technology of paving, made by the authors, gives the reader an opportunity to understand how technologically precise the process of building roads should be.

Published: July 2021

Abstract
This article describes the first stage of the research work on the development of FPGA-based cameras for vehicle identification tasks being widespread in automated points of weight and dimensional control. Since FPGA represents an alternative to conventional processors, which features the ability to perform multiple tasks in parallel, a camera equipped with FPGA will be able to perform vehicle detection and identification functions simultaneously. Thus, the camera will perform not only the transmission of the image but also the transmission of the processing result, after which the server will only need to confirm or deny the results of the camera operation, which will significantly reduce the processing time of images from all automated points of weight and dimensional control. A simple VGA port board, a program of a static image for displaying it on a monitor in 640x480 resolution, and a program for a pixel counter were implemented in the development phase. EP4CE6E22C8 is used as FPGA, which power is more than enough to achieve the result.

Abstract
The introduction in Russia of the Euro-5 standard and the tightening of rules on emissions of harmful substances has resulted in an overdue improvement in the methods and algorithms of calculation and design of toxicity decreasing systems to enhance the functioning of devices of these systems. Despite widespread methods of simulation and computer modelling for the study and testing of the proposed organizational and technical measures, it is relevant to assess the increase of exhaust recirculation motor units with the help of experimental studies. The purpose of the study is to evaluate emissions of harmful substances of the car exhaust and suggest an experimental device based on the apparatus and methodology for analysis of carbonyl compounds and volatile organic compounds. In assessing of the effectiveness of reducing the toxicity, significant attention is paid to methods of experimental studies. As an indicator of the effectiveness in reducing the toxicity of motor units, the volume of emissions of harmful substances was selected. The choice of the components of the experimental system for the automated processing of the environmental inspection results of motor vehicles was substantiated. These components are: software tools that implement the conduction of the test by a cold start of the engine and chassis dynamometer settings, as well as monitoring the progress of the experiment; interactive systems to transmit information between the posts of ecological police, private persons and legal entities, companies for the maintenance of vehicles.

Abstract
HHO gas (Brown’s gas) has recently been used as a new source of energy. The study presents the experimental results at 50% of the accelerator pedal when installed hydroxy (HHO) gas generator on 490 QZL diesel engines. HHO gas was provided into the engine manifold. Comparing the experimental results found that: the economic, technical and exhaust emissions of the diesel engine was improved. The brake power index increased by 2.8% in average compared to pure diesel and 4.2% was the percentage of the maximum engine power increasing at 2200 rpm. Especially, the amount of brake specific fuel consumption (BSFC) in pure diesel was always higher than one in diesel with HHO gas, which was 13.7% in average. At 1800 rpm, the difference of the minimum value of BSFC in two cases was 12.6%. The HC and CO emissions value reduced by 7.7% and 19.8% in average, respectively, while NOx increased by 13.3% in average compared to pure diesel.

Abstract
The report is devoted to the problem of building feedback with the car during its operation. It analyzes the problems that require feedback from the vehicle, clarifies the reasons why insufficient attention is paid to this issue, and discusses methods for obtaining the most informative data at the lowest cost. When working on the report, the authors relied on the results of their professional activities, which consists in the development and application in practice of diagnostic techniques for automobile internal combustion engines. The least costly and technically easy to implement is getting data from the engine management system controller. To increase the information content of such data, it is required to organize their correct processing and cataloging. You can get information about the progress of the working process in the engine cylinders by means of indication-direct or indirect. The implementation of direct indication is laborious and costly, therefore, with the help of direct indication, the authors of the report develop an indirect indication method based on the analysis of changes in the instantaneous crankshaft speed obtained as a result of processing the signal from the crankshaft position sensor. A promising complex of feedback with a car during operation should receive most of the data on engine operation from the ECM, but to calculate the generated torque, the complex must register a signal from the crankshaft position sensor using an ADC.
