Model-independent assessment of current direct searches for spin-dependent dark matter

open access: yes, 2004
I evaluate the current results of spin-dependent weakly interacting massive particle (WIMP) searches within a model-independent framework, showing the most restrictive limits to date derive from the combination of xenon and sodium iodide experiments. The

Xenon excimer emission from multicapillary discharges in direct current mode [PDF]

open access: yes, 2011
Microdischarges in xenon have been generated in a pressure range of 400–1013 mbar with a fixed flow rate of 100 sccm. These microdischarges are obtained from three metallic capillary tubes in series for excimer emission. Total discharge voltage is thrice

EEG driven tDCS versus bifrontal tDCS for tinnitus

open access: yesFrontiers in Psychiatry, 2012
Tinnitus is the perception of a sound in the absence of any objective physical sound source. Transcranial Direct Current Stimulation (tDCS) induces shifts in membrane resting potentials depending on the polarity of the stimulation: under the anode gamma ...

Direct current plasma spraying of mechanofused alumina-steel particles

open access: yes, 2009
Stainless steel particles (60 $\mu$m in mean diameter) cladded with an alumina shell (2 $\mu$m thick and manufactured by mechanofusion) were sprayed with an Ar-H2 (53-7 slm) d.c. plasma jet (I = 500 A, P = 28 kW, \rho_th = 56 %).

Antibacterial Effects of a Silver Electrode Carrying Microamperage Direct Current in vitro [PDF]

open access: yes, 1994
Currently, electrical stimulation is an accepted method used clinically to promote chronic wound healing. A literature review revealed that similar therapeutic current has been shown to suppress growth of common wound pathogens in vitro and in vivo.

Kohn-Sham equations for nanowires with direct current

open access: yes, 2003
The paper describes the derivation of the Kohn-Sham equations for a nanowire with direct current. A value of the electron current enters the problem as an input via a subsidiary condition imposed by pointwise Lagrange multiplier.

Management of Postsurgical Hyperhidrosis With Direct Current and Tap Water [PDF]

open access: yes, 2004
Background and Purpose. Excessive sweating, known as hyperhidrosis, involves the eccrine sweat glands of the axillae, soles, palms, and/or forehead. The use of iontophoresis to reduce or eliminate excessive sweating has been described since 1952.

Distributed Voltage and Current Control of Multi-Terminal High-Voltage Direct Current Transmission Systems

open access: yes, 2014
High-voltage direct current (HVDC) is a commonly used technology for long-distance power transmission, due to its low resistive losses and low costs. In this paper, a novel distributed controller for multi-terminal HVDC (MTDC) systems is proposed.

INVESTIGATION OF EXPLOSION SAFETY OF DC POLYMER SURGE ARRESTERS 3.3 KV FOR TRACTION NETWORK OF RAILWAY TRANSPORT

open access: yesElectrical engineering & Electromechanics, 2019
In the testing laboratories of Ukraine, there is no high-voltage equipment of the necessary energy for testing surge arresters for explosion safety, which does not allow to estimate this indicator at the stage of development of prototypes.
