Building Information Modeling-Based Secondary Development System for 3D Modeling of Underground Pipelines

Underground pipeline networks constitute a major component of urban infrastructure,and thus,it is imperative to have an efficient mechanism to manage them.This study introduces a secondary development system to efficiently model underground pipeline networks,using the building information modeling(BIM)-based software Revit.The system comprises separate pipe point and tubulation models.Using a Revit application programming interface(API),the spatial position and attribute data of the pipe points are extracted from a pipeline database,and the corresponding tubulation data are extracted from a tubulation database.Using the Family class in Revit API,the cluster in the self-built library of pipe point is inserted into the spatial location and the attribute data is added;in the same way,all pipeline instances in the pipeline system are created.The extension and localization of the model accelerated the modeling speed.The system was then used in a real construction project.The expansion of the model database and rapid modeling made the application of BIM technology in three-dimensional visualization of underground pipeline networks more convenient.Furthermore,it has applications in pipeline engineering construction and management.

Effects of Plant Secondary Metabolite Nicotine on Growth and Development of Frankliniella occidentalis

[Objective] The paper was to explore the chemical and molecular mechanisms of Frankliniella occidentalis, an important quarantine pest, against toxic substances. [Method] F. occidentalis were evaluated after continuous exposure to artificial diets containing nicotine from the 2^（nd） and the 3^（rd）instars for five generations, to determine the larval weight, pupal weight, and larval development duration. [Result] The larval development delayed and nicotine treatment significantly inhibited the weight gain of larvae. Compared to the control, the inhibition rates of larval weight and pupal weight were declined from 45% to 20% and from 25% to 4% respectively after feeding the 2^（nd）instars with nicotine for five generations.Nicotine delayed the larval growth and prolonged the generation duration of F. occidentalis. Nicotine showed more significant inhibitory effect on the lower instar larvae. With the increasing generations of secondary culture, the inhibitory effect of nicotine on larval weight and pupal weight was weakened. The developmental period of larvae was shortened, and the generation duration of F. occidentalis was shortened. [Conclusion] Nicotine affects the growth and development of F. occidentalis. F. occidentalis will gradually increase the adaptability to nicotine toxic substances after selfregulation for a few generations, and relieve the inhibitory effect of toxic substances.
