Abstract The gravitational force controls the evolution of Universe on several scales. It is responsible for formation galaxies from primordial matter distribution and planets solar nebulae. Because singular has infinite range, making predictions based fully three-dimensional models may be challenging. One-dimensional (1D) Newtonian gravity were proposed as toy understanding dynamics systems. T...

in this research we have studied tabriz temperature inversion using radio-sound information, during the 2004-2008 periods in daily, monthly and seasonally scales. produced data associated with temperature inversion daily of the surface (2 meters) to 700 h.pa. several different measures are used, including the height of the base and the height of the top of the inversion, the temperature at the ...

Chemical investigation of the EtOH extract from the tubers of Stephania succifera collected in Hainan Province of China resulted in the isolation of the two new alkaloids Cepharanone D (1) and N-formyl-asimilobine (2), and a known alkaloid, N-formyl-annonain (3). Their structures were elucidated by spectroscopic techniques (UV, IR, 1D and 2D NMR). The antimicrobial activities of the three compo...

We report the highly stable supercapacitive performance of one-dimensional (1D) nanoneedles of brookite (b) TiO2 synthesized on a conducting glass substrate. The 1D b-TiO2 nanoneedles synthesized over a large area array utilizing hot-filament metal vapor deposition (HFMVD) were 24–26 nm wide, 650 nm long and tapered in a downward direction. X-ray photoemission spectroscopy (XPS) revealed their ...
