Journal of materials Science and Chemical Engineering 2024年第6期12卷 12-23页

作者： Weiling chu Linling Wu Jing Yuan Qianfeng Zhang Institute of molecular Engineering and Applied Chemistry Anhui University of Technology Maanshan China Department of Civil Engineering Tongling University Tongling China Department of Civil Engineering Manitoba University Winnipeg Canada

With the vigorous development of China’s iron and steel industry and the introduction of ultra-low emission policies, the emission of pollutants such as SO2 and NOx has received unprecedented attention. At present, the commonly used denitrification methods include selective catalytic reduction (SCR), active coke, etc. As a newly developed denitrification technology, oxidation denitrification is not widely used, and the technical level is mixed, and there might be problems such as yellow smoke, secondary pollution and ozone escape in the practical application. In this paper, problems existing in the denitrification process of sintering flue gas oxidation are analyzed, and a 320 m2 sintering machine is taken as an example. Comparing the denitrification technology of sintering industry, it could be seen that the denitrification technology route of oxidation method has low pollution, low cost and high comprehensive environmental benefits, and has greatly potential development.

Glomerular organization in the antennal lobe of the oriental armyworm mythimna separata

Journal of Integrative Agriculture 2024年第11期23卷 3812-3829页

作者： Baiwei ma Qi Chen Xi chu Yidong Zuo Jiayu Wang Yi Yang Guirong Wang Bingzhong Ren Jilin Provincial Key Laboratory of Animal Resource Conservation and Utilization School of Life Sciences Northeast Normal University Key Laboratory of Vegetation Ecology Ministry of Education Northeast Normal University State Key Laboratory for Biology of Plant Diseases and Insect Pests Institute of Plant Protection Chinese Academy of Agricultural Sciences Chemosensory Lab Department of Psychology Norwegian University of Science and Technology Shenzhen Branch Guangdong Laboratory for Lingnan Modern Agriculture Synthetic Biology Laboratory of the Ministry of Agriculture and Rural Affairs Agricultural Genomics Institute at Shenzhen Chinese Academy of Agricultural Sciences

In insects, the number and specificity of antennal lobe glomeruli often reflect the number and diversity of expressed chemosensory genes, which are linked to its ecological niche and specific olfactory needs. The oriental armyworm, mythimna separata, is an important and common lepidopteran pest of cereal crops. Given its reliance on the olfactory system for crucial behaviors, understanding the evolutionary potential of this system requires a thorough characterization of the anatomical structure of the primary olfactory center. Here, we systematically identified all antennal lobe glomeruli of m. separata based on synaptic antibody immunostaining and mass staining of the olfactory sensory neurons. A total of 69 glomeruli were identified in females and 65 in males, and an intuitive nomenclature based on glomerular positions was applied. Our findings uncovered some sex-specific glomeruli in this species. There were ten female-specific glomeruli and three male-specific glomeruli, except for the macroglomerular complex(mGC) units, with a notable observation that the female labial pit organ glomerulus was larger than its male counterpart. Additionally, we identified four antennal-lobe tracts(ALTs) and retrograde labeling from the calyx revealed that all glomeruli were innervated by the medial ALT projection neurons. The comparison of the olfactory system structures between m. separata and sympatric moths supports their evolutionary convergence in noctuid moths. These results collectively lay the foundation for future studies on olfactory processing in m. separata.
