The determination of critical micelle concentration of selected non-ionic surfactants (Tween 20,40 and 80) have been investigated using magnetic water(MW)as an aqueous medium.Conductometry technique is used to determine critical micelle concentration.The effect of alcohol addition and temperature variation at the range(293.15 -303.15K) are also pursued. It is concluded that the process of micellization is spontaneous and endothermic because of the observed free energy of micellization (ΔGom) , enthalpy change of micellization (ΔHom), and entropy change of micellization (ΔSom) for the system was also studied.The properties of the non-ionic surfactants were studied, both in absence and presence of alcohol. The results obtained were explained in light of hydrophobic-hydrophilic interactions and chain length of alcohol.The temperature change has slight effect on the micellization process. .
Elements of the study contribute to the direction and demonstrate scientific steps, in order to walk in the implementation procedures. The researcher is a sense of a social phenomenon is an important step and a motivation to study and uncover the causes and factored in order to reach substantive results. And to clarify what is involved in the importance of the study, as well as setting goals that aspire to achieve the study . &nbs

The civil war in Seralion is considered as complex model of internal
conflicts in Africa because link to crises have relation to political, economical ,
social and cultural conditions, which were infected by disability and paralysis
in function performance, and what have effect on Seralion's relation
internationally or regionally.
In this research discussed three parts, the first is the factors of rise civil
war in Seralion , the second indicated the effected determiners in civil war in
Seralion , the third shown the factors of put end to civil war in Seralion .
The research concluded to significant reality that civil war in Seralion had
strategic effects on regional or international relations .
