This research provides an exploration of a biomimetic approach in the process of designing a candelabra model using linear shaped leaves of a Bell *** design process described in this research contains two steps:biological and *** the first biological step,a proper model for the creation of an urban element was found from nature in a Bell flower(Campanula persicifolia L.).The upper leaves of the selected plant,which are small with a linear spear and sharpening at the top,were chosen for the modeling *** second step included applying two geometrical methods,i.e.,Voronoi diagrams and Delaunay triangulation.A geometrical leaf form of the selected plant species and the modeling process were obtained using aparametric modeling software,*** different Blender plug-ins and modifiers,Delaunay triangulation and Voronoi diagram were implemented by marking the starting points on the leaf form in the image data source,adjusting the Delaunay triangulation parameters,and creating Voronoi diagrams in which the Voronoi points were located at the shortest distance from the edges of the Voronoi ***,a three dimensional model of a candelabra was developed through this study.

In the last decade,there has been an increasing interest in understanding the effects of changing injected water salinity on the performance of oil *** paper aims to investigate the effects of injected water salinity on oil recovery of an Egyptian oil reservoir(Bahariya formation).An experimental work program has been performed using 25 core plugs and 5 different water salinities to study the effects of changing water salinity during both secondary and tertiary stages of *** objectives of the experimental work were to(1)investigate the effects of the low water salinity on oil recovery and(2)identify the optimum water salinity and the main reservoir parameters for application of low salinity waterflooding project(LSWF)in Bahariya *** results revealed that there is an optimum salinity for waterflooding in the secondary flooding ***,for the tertiary flooding stage,the results showed that the controlling factor is not decreasing the salinity,but rather changing the salinity(*** increasing or decreasing).It was also clear that applying the optimum salinity in the secondary recovery stage is more effective than applying it in the tertiary recovery ***,the results showed that the positive impact of LSWF may be expected in reservoirs with high amount of kaolinite,high values of CEC,and low amounts of plagioclase *** study is an original contribution to develop guidelines for designing optimum salinity waterflooding projects in sandstone reservoirs.
