In this paper we analyze the problem of glow discharge in low pressure plasma in industrial plant, for chambers of different shapes and various working parameters, like pressure and electric potential...
Collisional kinetics of non-uniform electric field, low-pressure, direct-current discharges in H$_{2}$
non-uniform electric field low-pressure direct-current discharges
2010/11/16
A model of the collisional kinetics of energetic hydrogen atoms, molecules, and ions in pure H$_2$ discharges is used to predict H$_\alpha$ emission profiles and spatial distributions of emission fro...
Technical Note: Measuring condensation sink and ion sink of atmospheric aerosols with the electrical low pressure impactor (ELPI)
condensation sink ion sink atmospheric aerosols ELPI
2010/2/21
We investigate the suitability of ELPI for condensation sink and ion sink measurements. The aim is to find the simple calibration factors by which the measured ELPI current can be converted to condens...
A quantitative evaluation of the role of the Argentinean Col and the Low Pressure Tongue East of the Andes for frontogenesis in the South American subtropics
Argentinean Col Low Pressure Tongue East South American subtropics
2010/1/28
Previous studies have found the South American subtropics to exhibit high climatological frontogenesis in equivalent potential temperature during the austral summer. An important contribution to this ...

Clinopyroxene phenocrysts and microphenocrysts in different series of the Neogene alkaline volcanic rocks from the eastern Pontides (NE Turkey) record various stages in the crystallization conditions ...
Coring basalt under Mars low pressure conditions
Coring basalt Mars low pressure conditions
2009/6/1
We report and evaluate drilling results in hard basalt under Mars low pressure conditions and introduce an equation that may be used to estimate drilling performance in hard formations.
Technical note: Measuring tropospheric OH and HO2 by laser-induced fluorescence at low pressure. A comparison of calibration techniques
Measuring tropospheric laser-induced fluorescence low pressure calibration techniques
2008/10/27
The hydroxyl radical (OH) is one of the most important oxidants in the atmosphere, as it is involved in many reactions that affect regional air quality and global climate change. Because of its high r...

The electrical breakdown has been investigated for low-pressure argon and nitrogen discharges under the influence of an external longitudinal magnetic field. Plane-parallel aluminum electrodes (5 cm d...
Stability of high-Al titanite from low-pressure calcsilicates in light of fluid and host-rock composition
high-Al titanite low-pressure fluid and host-rock
2012/3/31
Our recent paper noted that °∞some of the existing [M?ssbauer] studies (e.g., Fuchs et al. 1995) should be discounted due to th
fact that peak widths are less than the theoretical minimum imposed by ...
