The radial structure of the continuous spectrum of shear Alfvén waves is calculated in this paper within the separatrix of a magnetic island. Geometrical effects due to the noncircularity of the flux surface’s cross section are retained to all orders. On the other hand, only curvature effects responsible for the beta-induced gap in the low-frequency part of the continuous spectrum are kept. Mod...

Vegetation changes of tropical Lizard Island (Great Barrier Reef World Heritage Area, Australia) over the last 8000 years are derived from palaeoenvironmental analysis of a 475 cm long sediment core. During early-Holocene sea-level rise, flooding of the continental shelf and thus isolation of Lizard Island, the pollen record shows the gradual establishment of a mangrove forest paralleled by con...

Chongming Island, the third largest island in China, has experienced dramatic shoreline changes due to erosion, river deposits, and human activities. While previous studies have shown capacity of Landsat series images extract dynamics, spatial variation dynamics their corresponding driving factors remain unclear. Therefore, we established a method monitor Island from 1984 2020 evaluate using no...

The radial structure of the shear Alfvén wave continuous spectrum is calculated inside the separatrix of a magnetic island. We find that, within a magnetic island, there is a continuous spectrum very similar to that of tokamak plasmas, where a generalized safety factor q can be defined and a wide frequency gap is formed, analogous to the ellipticity induced Alfvén eigenmode gap in tokamaks. Thi...

Background: Drugs play a strategic role as a health commodity. Thus, the supply chain management of drugs is an important issue to reducing costs and thereby improving patient health. Objective: This study evaluated the status of drug supply chain management and health reform in the pharmaceutical sector of teaching hospitals in Ahvaz, Iran. <strong...

The impression gained from the literature published to date is that the spectrum of the stadium billiard can be adequately described, semiclassically, by the Gutzwiller periodic orbit trace formula together with a modified treatment of the marginally stable family of bouncing ball orbits. I show that this belief is erroneous. The Gutzwiller trace formula is not applicable for the phase space dy...

An unusual eastward flow was observed branching out from the Kuroshio Current near island of Taiwan in western North Pacific during period June–July 2010. The branch meandered approximately 21°N, carrying high chlorophyll-a (Chla) waters for over 1000 km 125°E into nutrient-poor subtropical gyre (NPSG). warmer and fresher than surrounding waters, with temperature–salinity properties resembling ...
