Abstract:
This research explores the documentation and preservation of the historical building “Al-Ghulitha outpost” using engineering software. The study emphasizes the significance of integrating engineering methodologies with cultural heritage conservation. The documentation process involved collecting historical information and site surveys for data gathering and applying AutoCAD and SketchUp software to create the 2D site plan and 3D model precisely. Moreover, using engineering software such as Lumion has enhanced visualizations of what a building might have looked like earlier. Based on these visualizations, it is possible to know the damages to which the building’s structure has been exposed, determine their locations, and clarify the potential maintenance effects. As a result, these results were adopted as a basis for damage diagnosis and the provision of an initial conservation plan.
The study demonstrates the importance of documenting and preserving Al Ghulitha as a model of late Ottoman architecture and stresses the importance of integrating engineering techniques with elements of culture and history. The study achieved high accuracy in documenting the case study using engineering software and illustrated the importance of this balance in enhancing conservation efforts and ensuring the continuity of heritage. Moreover, this research also saves time and effort in identifying damages in historical buildings before maintaining them. The results indicate the need to spread cultural awareness and include the local community in interacting with cultural activities and planning for future maintenance. The research draws attention to the importance of historical buildings and indicates the need to take the necessary measures to protect them, including funding and legislation, within the framework of integrated cooperation between heritage preservation experts and engineers.

Abstract
Ziziphus spina christi and Ficus carica are known for their activities and use in traditional medicine in treating many diseases besides being nutritious and healthy for eating. This study evaluated antioxidant activity in the bark and leaves, ethanoic extracts of Ziziphus spina Christi (L.) and the aqueous extract of Ficus carica. The extract’s antioxidant activity was measured based on the scavenging activities of the established 1,1-diphenyl-2-picrylhydrazyl free radical scavenging method. The total antioxidant activity was measured using Total Antioxidant Capacity Reagent (TCA), using a UV- spectrophotometer against a blank, At the same time, the standard was a series of Ascorbic Acid solutions. The results revealed that the leaves extract of sider and f. carica has total antioxidant activity less than the sidr bark extract which was 300, 40 and 700 respectively. IC50 of fig leaves extract was 260.228 µg/ml and of sider leaves and bark extract were 124.433 & 1.7924 µg/ml respectively while it was 50.558 µg/ml for ascorbic acid. The low concentration of sider park has more antioxidants activity comparing with leaves from both sider and fig.

Abstract
In this research, a mathematical model was created to study the performance of the development of basic design of dual electro thermal centers dedicated to the production of electric energy and desalinated water together. In the form of a measure of the effectiveness of the heat and maintaining the lowest level of pollution of the surrounding medium , for electricity and desalinated water together , in the proposed design compared to the independent production of electric power and desalinated water through a processing plant and reverse osmosis desalination unit .The effect of multi-effect evaporated desalination unit and the gas turbine unit , as well as the thermodynamic thermal properties of this unit , were compared with the basic design of the steam plant . The result of the study has been shown:
The effectiveness of using dual-pressure double –phase in the development of steam station to the centers of electro thermal. Where the minimum savings in the amount of fuel consumed 77.9 kg/hr to MW (Mega Watt ) .of electric energy produced in the basic design of the steam plant and the lower resulting pollution rates such as a nitrous oxide( 0.26 kg/MW.hr ) , and carbon dioxide present in the air pressure supplied to the desalination unit from 0.3 bar ,( as result of this improvement , the design number of the effects of desalination unit =8 ,and the water quantity produced 15.7 ton/MW.hr ) .
High pressure steam supplied to the desalination unit from 0.3 bar to 0.38 bar, and the high quantity of desalination water produced by 15.3 %, as well as decrease in the electric power produced by the steam turbine unit ay rate of 2.9 %.
Thermal and environment performance of the use of successive gas turbine unit in the development of steam turbine to the centers of electro thermal ,where the lowest level of increase by the amount of fuel consumed and environment indicators above 14.9 %.
