I. Characteristics of Removal of Hydrophobic Organic Carbons from Sand/Mulch Using Nonionic Surfactants
Accepted at Journal of Land contamination 2009.
In this study a nonionic surfactant, Triton X-100 was used to study the sorption characteristics of organic contents in soil. The surface tension is used for calculating this kind of sorption. The results indicated that when the concentration of surfactant was lower than the CMC, the amount of surfactant sorbed on soil increased with the increasing surfactant concentration and the surfactant sorption characteristics of the uncontaminated soil could be modeled by the Freundlich isotherm. For the contaminated soils, the amount of surfactant sorbed was higher than those for the uncontaminated soils.

Accepted at Journal of Research chemistry and Physics 2007.Abstract
This research study investigated the relationship between the organic content of soils and the sorption characteristics of a non-ionic surfactant, Triton X-100. The experiments were performed using uncontaminated soils and soil contaminated with naphthalene. The sorption of Triton X-100 was calculated from the surface tension measurements. The second part of the experiments utilized the SPME/GC/FID technique to determine the concentration of the contaminants solubilized from the soils by the surfactant Triton X-100 at different concentrations.
The results indicated that when the concentration of surfactant was lower than the CMC, the amount of surfactant sorbed on soil increased with the increasing surfactant concentration and the surfactant sorption characteristics of the uncontaminated soils could be modeled by the Freundlich isotherm. For the contaminated soils, the amount of surfactant sorbed was higher than those for the uncontaminated soils. The amount of surfactant sorbed on soils also depends on the organic content in the soils. The higher the organic content in the soil, higher is the amount of surfactant sorbed onto the soil. When the concentration of surfactant was higher than the CMC, the amount of surfactant added into the soil/aqueous system will increase the number of micelle and it increase the solubilization of organic contaminant from the soils. The ratio of the moles of organic contaminant solubilized to the moles of surfactant present as micelles is called the molar solubilization ratio (MSR). MSR value for naphthalene was about 0.16 for the soil-water systems. The organic content of soil did not appear to affect MSR for naphthalene.

III.SORPTION CHARACTARESTICS OF NONIONIC SURFACTANT IN SOIL CONTAMINATED WITH DECANE.
Accepted at Journal of Land contamination 2008.Abstract
Hydrophobic and non-polar organic carbon compounds have low aqueous solubilities, and the biodegradation of such compounds may be restricted because of the low solubility coupled with strong binding/sorption onto solids.
The main goal of this research is to study the factors affecting the surfactant sorption on soil such as surfactant concentration, soil organic content, and removing organic contaminant like decane from soil using nonionic surfactant, Triton X-100.
The results indicated that when the concentration of surfactant was lower than the CMC, the amount of surfactant sorbed on soil increased with the increasing surfactant concentration and surfactant sorption characteristics of the uncontaminated soils could be modeled by Freundlich isotherm. For the contaminated soils, the amount of surfactant sorbed was higher than those for the uncontaminated soils. The amount of surfactant sorbed on soils also depends on the organic content in the soils. When the concentration of surfactant was higher than the CMC, the amount of surfactant added into the soil/aqueous system will increase the number of micelle and it increase the solubilization of organic contaminant from the soils. Measurements of surface tension were used for our analysis to gain the data and conclusion from this study.

Energy Research Centre
Academy Education Development (AED)
According to our knowledge this project represents the first realistic practical and professional project on utilizing wind energy in Palestine. The project facilitates the creation of a data base on solar and wind energy parameters through implementation of field measurements on three promissing sites in Palestine using modern computerized data acquisition stations. The characteristics of wind and solar energy in the selected sites which represent many other locations in Palestine became through this project well known. The project facilitate the procurement of wind electric energy converter which will be very useful for university education, training and research purposes.
Furthermore, this project has effectively supported the upgrading of know how and capabilities on wind energy at the Energy Research Centre of An Najah National University, which is candidate to lead all solar and wind energy activities in whole Palestine.
Therefore, the An Najah National University like to express its thanks and gratitude to the Palestinian Ministry of Higher Education and to the AED – Organization for supporting and financing the Implementation of this vital and advantageous project.
The main goals of this project were set to :
1-Determination of wind energy potential in some representative selected sites in the West Bank of Palestine .
2-Investigating of the possibility of wind electric power generation in the selected sites.
3-Establishment of data base on wind energy at the Energy Research Centre of An Najah National University.
4-Demonstrating the possibility of Utilizing of wind energy in electric power generation in the West Bank.
5-Facilitating the education, training and research in the wind energy field at the An Najah National University.
The implemented activities in this project are summarized in the following points:
1-Investigating of several sited in the West Bank which were considered to have wind energy potential and selecting three sites for erection of the automatic measuring stations.
2-Erection of measuring station in the selected sites where, wind velocity, wind direction, solar radiation, relative humidity, ambient temperature and atmospheric pressure, were continuously measured.
3-Evaluation of measuring results
The obtained measuring results were analyzed and evaluated on hourly, monthly and annual basis. A sample of the evaluation results is attached in the Annex 1. These results show that daily average wind speeds achieving 10.5 m/s have been measured. On annual basis an average wind speed of 4.25 m/s has been registered . This velocity is an indicator for moderate Wind energy potential in the selected sites. On other hand this velocity is appropriate for some applications as water pumping and electrification of small isolated small communities and farms. The measuring process will continue after finalizing of this project because an exact determination of wind energy potential in any site requires the measurement of wind velocity and direction for at least three successive years. This activity will result in establishing a data base on wind and solar parameters which will be essential for development and popularization of alternative energy applications in Palestine.
4-Laying out the specification of the Wind Energy Machine Based on the gained measuring results indicating that the average wind velocity is only moderate (2.5 – 5 m/s) , and considering the budget limitation of this project (total 6000 US $) , it was concluded that a three blade wind turbine of 1 kW rated power would be very appropriate for this pilot project.
A tender document including the technical specifications of the 3 – blade wind electric converter had been prepared and transferred to the Procurement Department at the University. This department has opened the tender and got limited offers due to the minor number of local companies working in wind energy and to the small volume of the project budget. An appropriate offer presenting a three blade wing turbine meeting the layed out specifications has been selected. This turbine is rated at 1kW by a wind speed of 13.5 m/s. A copy of the offer illustrating the respective offer and specifications is attached in Annex 2.
A testing program for measuring the various characteristics of the wind turbine has been prepared. This program enables the electrical, mechanical and industrial engineering students to execute their final graduation projects on this machine and facilitate the implementation of research activities.
Wind Power Results:
According the illustrated obtained measuring results, the mentioned wind electric turbine will produce about 265 kWh per year which corresponds to 726 wh / day on annual basis. However, with respect to the illustrated wind speed results , the wind machine will deliver in some days 7kWh / day.
Prospectives and Future Activities:
As mentioned before, this project has opened the door leading to the education, training and research in the wind energy field at An Najah National University. Starting in the first semester 2005/2006 many research and graduation projects will be carried out utilizing the procured wind turbine and the results of the measuring stations. The energy Research Centre will search for financing resources allowing the procurement of larger wind electric converters to be used for different applications as water pumping electrification of small isolated communities and villages and grid connection. It is hopped that the Energy Research Centre will perform such a project in cooperation with a competence partner from USA or the European community where know how and experience in the wind energy
