Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：On the Finite-Time Splash for the free boundary incompressible Navier–Stokes equations (I)
自由边界 不可压缩 Navier-Stokes方程 有限时间飞溅
2023/5/18
In this talk, we consider the incompressible Navier-Stokes equations with free boundary, which has a finite-time splash singularity for a large class of specially prepared initial data. The approach i...
Splash erosion in maize crops under conservation management in combination with shallow strip-tillage before sowing
aggregate stability conservation tillage mulch plants cover plants residues silage maize soil protection
2017/6/26
Soil under maize cropping is among the most endangered by erosion. The effect of conservation tillage management on values of splash erosion when using shallow strip tillage before sowing maize was ev...
Effect of row width on splash erosion and throughfall in silage maize crops
erosion growth stage leaf area index plant length precipitation
2017/4/6
Line width is one of the major factors affecting arable soil erosion. The aim of the study was to assess the effects of different row spacing on splash erosion and throughfall in maize crops. Field me...
羟基（OH）分子是星际介质中首次被探测到的分子，于上世纪六十年代被探测到，基态OH脉泽也是首次被探测到的天体脉泽。类似于激光是在光学波段的一种受激发射，脉泽是在微波波段的一种受激发射。目前已经探测到的天体脉泽分子种类包括：水、甲醇、氧化硅及其同位素、甲醛、氰化氢及其同位素等。OH分子的结构简单，其脉泽具有多条谱线跃迁，其中以波长在射电L波段（频率包括：1612、1665、1667和1720兆赫兹）...
Affectability of splash erosion by polyacrylamide application and rainfall intensity
marl formation polyacrylamide FEL3 rainfall simulator splash erosion
2015/3/5
Splash erosion is recognized as the first stage in a soil erosion process and results from the soil surface bombing by rain drops. At the moment when rain drops conflict with the soil surface, soil pa...
Thermal shock and splash effects on burned gypseous soils from the Ebro Basin (NE Spain)
Thermal shock splash effects gypseous soils the Ebro Basin
2015/1/6
Fire is a natural factor of landscape evolution in Mediterranean ecosystems. The middle Ebro Valley has extreme aridity, which results in a low plant cover and high soil erodibility, especially on gyp...
ON THE ABSENCE OF "SPLASH" SINGULARITIES IN THE CASE OF TWO-FLUID INTERFACES
SPLASH SINGULARITIES TWO-FLUID INTERFACES
2014/4/3
We show that "splash" singularities cannot develop in the case of locally smooth solutions of the two-uid interfaces in two dimensions. More precisely, we show that the scenario of formation of singul...
18 May 2007，Ever jammed a sword up your nose? Not something to try at home, folks, but accidents do happen. Dr Matt Jones, an RCUK Academic Fellow in the Department of Physiology, tells us what happen...
