Non-traumatic exertional rhabdomyolysis (exRML) occurs in individuals with normal muscles when the energy supplied to the muscle is insufficient. Here, we report 11 cases of spinning-induced rhabdomyolysis and review related literature. Spinning is a kind of indoor bicycle sport. The 11 patients who were diagnosed with exRML and admitted to CHA Bundang Medical Center were female and their ages ...
This paper surveys recent progress in fiber spinning technology for reducing polarization mode dispersion with the focus on theoretical understanding of fiber spinning mechanism and features of spun fibers, as well as their applications in fiber spin profiles designs. First, a brief introduction to the requirements of fiber PMD for high-speed optical fiber communications systems is given. Furth...
The Spinning Screen In screen-based experiences, the screen itself can become the physical device used for interaction. The “move-ability” of the screen affords interactivity between the screen artifact and the viewer and between the virtual space and the physical space. As a movable screen interface, I have created the spinning screen, a two-sided monitor mounted on a revolving base. This inte...
Water in Silicate Glasses: Quantitation and Structural Studies by 'H Solid Echo and MAS-NMR Methodst
'H wideline and magic angle spinning (MAS) NMR results are reported for water in a series of synthetic and naturally occurring silicate glasses containing from 0.04 to 9.4 wt % H20. For glasses free of paramagnetic metal ions, the absolute water contents can be accurately determined by a solid echo IH NMR technique with pyrophyllite, A12Si,010(OH)2, as an intensity reference. The MAS-NMR spectr...
This document proposes a definition of spinning reserve. It also compares the amount asked by TSOs in several systems according to this definition. What is spinning reserve?
Cobalt-based amorphous alloys attracted the attention of many researchers to carry out fundamental research for their application in electronics, sensors and magnetic memory due to their special magnetic properties including close to zero Magnetostriction, magnetic permeability and high saturation magnetization. The purpose of this study is the formation and evaluation of microstruct...
This paper addresses the bidding problem faced by a virtual power plant (VPP) in energy, spinning reserve service, and reactive power service market simultaneously. Therefore, a non-equilibrium model based on security constraints price-based unit commitment (SCPBUC), which is take into account the supply-demand balancing and security constraints of VPP, is proposed. By the presented model, VPP ...
Strategic bidding in joint energy and spinning reserve markets is a challenging task from the viewpoint of generation companies (GenCos). In this paper, the interaction between energy and spinning reserve markets is modeled considering a joint probability density function for the prices of these markets. Considering pay-as-bid pricing mechanism, the bidding problem is formulated and solved as a...
The application of FeSiB family magnetic materials in the electrical or electronic industry has significantly increased owing to development amorphous and nanocrystalline metallic glasses using melt spinning chill block technology, which involves a rotating metal wheel with high rotation speed. With this technique, thin ribbon is obtained jet liquid expelled from casting nozzle at pressure temp...
A new chelating matrix has been prepared by immobilizing 1,8-dihydroxyanthraquinone (DHAQ) on silica gel modified with (3-aminopropyl)triethoxysilane. After characterizing the matrix with thermogravimetric analysis (TGA), cross polarization magic angle spinning (CPMAS) NMR and diffuse reflectance infrared fourier transformation (DRIFT) spectroscopy, it has been used to preconcentrate Pb(II), Cd...
