Diurnal plasma glucose profiles and oral glucose tolerance during pregnancy were studied in normal women, chemical diabetics, and insulin-requiring diabetics. In normal women the mean diurnal plasma glucose rose by only 0.22 mmol/1 (4 mg/100 m1) during pregnancy. Mild chemical diabetes resulted in an increase in both the mean diurnal glucose concentration and the fluctuation of plasma glucose l...

Charging currents of electrons and ions to a spherical dust grain in a uniform magnetized dusty plasma have been examined. It is found that the external magnetic field reduces the charging currents, thereby decreasing the dust charge fluctuation damping of a low-frequency electrostatic wave in a dusty plasma.

At certain values of the edge rotational transform ιa , the confinement quality of plasmas in the Wendelstein 7-AS (W7-AS) stellarator is found to react very sensitively to small modifications of the edge rotational transform ιa . As ιa can be reproducibly changed either by external fields or by a small plasma current, these transitions offer a precise way to systematically analyse differences ...

Short exposure photographs capturing the momentary state of the plasma radiation are often used for the primary characterization of discharges. Sequence of such images gives an impression about a variation of radiation intensity in different areas and can be used to describe the fluctuation intensity. This work presents a statistical procedure which produces brightness fluctuation intensity map...

The electron temperature gradient (ETG) mode, which is a universal mechanism for turbulent electron thermal transport in plasmas, is produced and verified in steady-state, collisionless hydrogen plasma of the Columbia Linear Machine. Electron temperature profiles with strong gradients are produced by DC acceleration in a remote biased mesh and subsequent thermalization. Finite amplitude 5%, ste...

In a previous paper [l] we have established a set of equilibrium fluctuation formulas for the quantum one-component plasma (OCP) in a magnetic field. The method we used was the so-called equation-of-motion method. In this way we have been able to derive a complete set of fluctuation formulas for the charge density, the current density and the energy density. Once these fluctuation formulas are ...
