A study of sludge characteristics of Biological Treatment by Extended Aeration at Merge Maarban station

The determination of sludge characteristics of wastewater treatment process has the primary role in the treatment and disposal. This research aims to determine the sludge characteristics by studying specific resistance factor of the sludge on the filtration at Merge Maarban station, so we took samples of sludge from the station and made several laboratory experiments and we got the time of intensify sludge, moisture and The concentration of the solid substances. we calculated specific resistance factor values of the sludge when the moisture values are ( 97.5 , 95.5 , 94 , 92 , 91 , 88 ) %. The research results showed a decrease in resistivity factor value of sludge on the filtration as its moisture become less and the sludge drying time takes tow weeks.

Study the ellectriicall propertiies off Co Zn - ferriites doped by Nii at diifferent frequenciies

This work includes study of Co Zn-ferrite samples doped by Ni which prepared by Ceramic method. Then verified that it had spinel structure by using XRD. In addition we study properties such as electrical resistivity , electrical conductivity , dielectric constant and loss coefficient. And also we have studied variations of this properties in terms of temperature at different frequencies in the range of (20 -105) Hz.

"Illumination on quantitative interpretation of the vertical electrical sounding curves"

Paper Find the possibility of interpreting the vertical electrical sounding curves in real field , having been reached resistivity virtual account through the equation is valid for all configurations V(r)=I/2 πr[C1pn+T() + C2p1] Search results provide a lot of time and effort in processing and interpretation of the geoelectrical data , and reflected positively on the interpretation of the vertical electrical sounding academic and an applied.

The use of sonic method in the detection of petroleum reservoirs in Syrian oilfields ( Jubiseh)

The use of sonic method to detect reservoirs with secondary porosity (fissures and cavities) was due to the high effect of this porosity on the elastic waves. The generalization of the experimental results helped to construct a diagram to be used in detecting reservoirs with secondary porosity in the wells. A joint analysis of the data of the sonic method and other well logging methods, such as boreborehole diameter log, natural radioactivity log, natural log and micro and deep resistivity log...etc, was achieved. The wave spectrum was analysed for a relatively long period so that it included Lambi waves. The detection of these reservoirs was achieved by using the correlation between all available results, which led to the determination of the presence of the secondary porosity and the suggestion of a new calculation method. In addition to the secondary porosity some other factors which affect the sonic measurements were mentioned.
