Anthranilic diamides are one of the most important classes modern agricultural insecticides. To discover new structure-modified compounds with high activity, series novel carbonyl thioureas, ureas, oxadiazoles, thiophosphorylureas, oxadiazole-containing amides, and thiazoline-containing amides were designed through modification amide bridge based on structure chlorantraniliprole synthesized, bioassays carried out. The characterized confirmed by melting point, IR, (1)H NMR, elemental analyses...

Two series of anthranilic diamides containing acylthiourea and acylurea linkers were designed synthesized, with changed length flexibility the to compare known diamide insecticides. In total, 26 novel compounds all characterized by 1H nuclear magnetic resonance high-resolution mass spectrometry. Their insecticidal activities against oriental armyworm (Mythimna separata), mosquito larvae (Culex pipiens pallens), diamondback moth (Plutella xylostella) evaluated. The larvicidal indicated that...

Twenty-two new benzoylphenylureas containing isoxazoline and the isoxazole group were designed synthesized, their structures characterized by (1)H NMR elemental analysis (or HRMS). The larvicidal activities against Oriental armyworm, mosquito, diamondback moth of compounds evaluated. Compounds I-1 III-1 showed nearly same level insecticidal activity armyworm as commercial insecticide Flucycloxuron surprisingly exhibited much higher than Flucycloxuron.

Summary One‐dimensional transient wave propagation in a saturated single‐layer porous medium with fluid surface layer is studied this paper. An analytical solution for special case dynamic permeability coefficient k f → ∞ and semianalytical general an arbitrary are presented. The eigenfunction expansion precise time step integration methods employed. presented series form, thus, the long‐term responses of media small coefficients can be easily computed. We first transform nonhomogeneous...

This paper introduced the adoption of a Track Sensor on satellite STSS to improve precision STSS. The concepts space coverage were proposed and corresponding models established. A simplified computation strategy was obtain simulation results. Space rate under different scenarios simulated as well its characteristics illustrated. Finally, valuable result about optimal orbit altitude for given working distance regardless specific constellation obtained.

This study employed a modified elastoplastic constitutive model that can systematically describe the monotonic and cyclic mechanical behaviors of typical marine soils combining subloading, normal, superloading yield surfaces, in seismic response analysis three-dimensional (3D) site. New evolution equations for stress-induced anisotropy development change overconsolidation were proposed. unified behaviour unsaturated soil saturated using independent state variables uniquely multiple...

Infrared (IR) image analysis is important for extracting IR anomaly features in the fundamental experiments of Remote Sensing Rock Mechanics (RSRM) and identifying omen tectonic earthquake based on satellite remote sensing monitoring. Transferring into a raster contour map very useful, but usually transferred not smooth enough disturbance noise limitation spatial resolution image.
