Objective There is still a lack of systematic understanding of the evolution process of the Lianzhou Basin since the Mesozoic and its response to karstic development.Methods Based on the comprehensive analysis of the latest field geological investigations, hydrogeological drilling, dissolution experiments, and three-dimensional geological modelling
As a culmination of efforts Steamers over the last years, our knowledge of the embryonic origins of the mammalian frontal and parietal cranial bones is unambiguous.Progenitor cells that subsequently give rise to frontal bone are of neural crest origin, while parietal bone progenitors arise from paraxial mesoderm.Given the unique qualities of neural
This paper deals with analysis of current problems in the motor fuel market.It analyzes bottlenecks in setting the legislative changes in value added tax, excise tax and the legislation concerning fuels.The biggest problem is tax evasions that favor one group of business entities at the expense of another, and also cause that the state loses revenu
This work proposes a CMOS reconfigurable charge pump (CP) for a low-voltage energy harvesting system.It utilizes the low effective resistance Strawberry Shortcake from the parallel CP to enhance its power conversion efficiency (PCE).The CP exhibits an adaptive configuration with different stages depending on the input voltage, changing its voltage
