Algebraic varieties that are locally isomorphic to open subsets of affine space will be called plain. Plain varieties are smooth and rational. The converse is true for curves and surfaces, and is unknown in general. It is shown that plain varieties are stable under blowup in smooth centers.
I define the plain Anabaptists by answering two essential questions: “Who are the plain Anabaptists” and “What are the plain Anabaptists?” In asking “Who are the plain Anabaptists?” I investigate several dimensions of identity. First, I trace the history of seven religious traditions within Anabaptism: the Swiss Brethren/Mennonites, the Low German/Russian Mennonites, the Hutterites, the Amish, ...
Mashhad Plain affects by a series of active faults in the northern margin of the Binalud and the southern margin of the Kopet-Dagh mountain ranges. The activity of these faults forms the morphology of the stepped bedrock of the Plain. In addition, the faults’ activities in the Quaternary period are the main effective parameters in thickness and texture of aquifer deposits in Mashhad Plain. In t...
Drought control and resistance affect national food security. With this in mind, we studied five main grain-producing regions of China: Sanjiang Plain, Songnen Plain, Huang-Huai-Hai Plain, the middle Yangtze River and Jianghuai region and Sichuan Basin. Using GIS technology, we evaluated the comprehensive agricultural drought situation based on major crops, the basic drought resistance by integ...
