The principal aim of the study was to examine the psychometric properties and construct validity of the General Decision-Making Scale (GDMS) in a sample of 700 adolescents (aged 15-19 years). Confirmatory and exploratory factor analyses provide evidence for a solid five-dimension structure reflecting the theorized construct: rational, intuitive, dependent, avoidant and spontaneous. No differenc...

A DC-driven ”barrier” discharge is a gas discharge layer and a high-Ohmic semiconductor layer sandwiched between planar electrodes to which a DC voltage is applied. The system resembles a dielectric barrier discharge, but is even simpler, as the external boundary conditions allow for a completely homogeneous and stationary state. Whole phase transition diagrams to purely oscillating states or t...

Joung-Hu Park Jong-Bok Baek Bo-Hyung Cho Abstract — Recently, a mercury-free flat fluorescent lamp has been developed for LCD backlight application, utilizing a glow-discharge mode instead of a discharge contraction. This paper proposes a lamp-driving system with a feedback loop which prevents discharge contraction and stabilizes the operation of the lamp ignition and radiation. By measuring th...

A cold plasma switch scheme with opening and closing capabilities is reported. An externally applied magnetic field causes a low pressure hollow cathode discharge to transition from a low impedance mode sustained by oscillating beam electrons into a virtually collisionless high impedance mode. The impedance of a 10 A discharge was demonstrated to increase by 20 with the application of a field o...

Here we present a novel visible analog computing approach for solving a wide class of shortest path problems. Using a microfluidic chip for computation, based on the lighting up of a glow discharge, the solution to maze search problems, the solution of a network shortest path and k-shortest paths problems and the practical application of finding the shortest paths between several landmarks from...

An excitation-emission model for the H2 IΠ +/− g −BΣu transition has been developed based on the coronal equilibrium. Within the framework of the adiabatic theory, the vibronic transition probability is calculated instead of the Franck-Condon factor. The ro-vibrational temperatures are evaluated through the experiment carried out in a low-density hollow-cathode plasma. The evaluated temperature...

It is shown that ac discharges propagating at an air / dielectric interface, though of planar structure, behave, till a critical voltage Vcrit, as corona discharges in an air gap, with similar propagation fields for the filamentary discharge components and similar glow components. This leads to consider the surface discharges as gas discharges propagating above the dielectric surface. Beyond Vc...

The effect of comparatively small pressure changes on the composition of low pressure hollow cathode DC discharges is investigated with a combination of experimental diagnostic techniques and simple models of the plasma kinetics. The plasma precursors considered are H2, Ar/H2 mixtures, and air. In all cases, sudden characteristic composition changes are observed in the pressure interval between...

This paper gives an overview of the main chemical processes which take place in cold plasmas generated in glow discharges, both in the gas phase and at the surfaces in contact with the plasma. Illustrative examples are provided where the relevance of different processes is evinced. Most common plasma characterization techniques and their recent improvements are also presented briefly.

Microdischarge devices (MDs) share many properties with their macroscopic counterparts while having unique features resulting from their ability to sustain large current densities and power depositions on a continuous basis at pressures approaching atmospheric. The dynamics of cylindrical, metal–dielectric–metal sandwich MDs sustained in Ar having characteristic sizes of a few hundred micrometr...
