In this work, we carried out an experimental study of thedusty
plasma by taking the dust material Fe3O4 with radius of the any grain
0.1μm - 0.5μm. In experiment we use air in the vacuum chamber
system under different low pressure (0.1-1) Torr. The results
illustrated that the present of dust particles in the air plasma did not
effect on Paschen minimum which is 0.5 without dust and with Fe3O4
dusty grains.
The effect of Fe3O4 dust particles on plasma parameters can be
notice in direct current system in glow discharge region. The plasma
parameters which were studied in this work represent plasma
potential, floating potential,electron saturation current, temperature
of the electron, the density of the (electron, ion), and Debye length.
The measurements of parameters are taken by four cylindrical probes
which diagnosed at distance 4cm from the diameter of the cathode in
Paschen minimum at pressure 0.5 Torr. The diameter profiles of
plasma parameters in the present of dust are non- uniform. Plasma
potential and the floating potential of probe becomes more negatively
when the dust immersed into plasma region. The electron density
increases in the present of dust particle which lead to decrease the
electron temperature and Debye length. The behavior of those
parameters shows the discharge current and discharge voltage
increases without dust while the discharge current and voltage
decreases when Fe3O4 dust particles embedded.
Global Navigation Satellite System (GNSS) is considered to be one of the most crucial tools for different applications, i.e. transportation, geographic information systems, mobile satellite communications, and others. Without a doubt, the GNSS has been widely employed for different scientific applications, such as land surveying, mapping, and precise monitoring for huge structures, etc. Thus, an intense competitive has appeared between companies which produce geodetic GNSS hardware devices to meet all the requirements of GNSS communities.

This work used two methods to monitor urban expansion and it's environmental and safety effects, the first is based on Google Maps for the years 2002 and 2010, and the second was the usage of spatial videos for the year 2013. Although the usage of satellite images is critical to know and investigate the general situation and the total effects of the expansion on a large piece of area, but the Spatial videos do a very detailed fine scale investigation, site conditions regarding both environmental and safety cannot be easily distinguished fr
