Architects started to get back to nature to look for the keys for building sustainability, because elements of nature are a   creative, rich, and useful  source  of  inspiration   and   learning   for architects and designers to present sustainable designs. Getting inspired by or simulating living forms should not lead to making exact copies of them. The real lesson is to benefit from the substantial idea and the basis of the natural system composing it. This leads us to the problem of the present study: There are no enough local studies on the importance and role of living nature simulation in terms of shape, composition, and structural systems to create sustainable   systems.  Hypothesis of the  study  is:  the  harmony shown  by natural, organic structures resulting from the integration of shape with structural function can be employed in architecture shapes and structures by merging shape and function in a symbiotic relationship resembling to a great extent biological , genetic development in their re-formations appearing in natural organic structures.

The importance of this aspect lies in the development of various sectors starting with architecture, urban development, as well as its contribution to the balance of performance and job creation, and its positive impact on the other sectors of the industry and trade in general, and architecture in particular. Architecture forms the physical and cultural dimension of tourism, all tourist activities are held in architectural facilities and many of the architectural facilities have become important tourist attractions. This creates a positive correlation between economic, social, urban development and the preservation of resources including the cultural heritage, especially those related to architectural heritage and traditional urban figures. Where sustainable tourism can be viewed as an industry that fulfills the functional need of the tourist without prejudice the location which to be invested, especially when the site has a historical or cultural significance or even the collective memory of the community. Therefore, the research problem focused on the knowledge deficit in studying the aspects of sustainable development and its role in tourism and its mutual effects on the urban heritage of cities in terms of their points of view and indicators and how to deal with them in order to achieve sustainable tourism for those places, If we consider sustainability is the environmentally conscious in tourism and architecture. The aim of this research is to draw the aspects of sustainable tourism in all its intellectual and applied dimensions and their impact on the urban heritage sites in order to promote these places to achieve the highest possible efficiency for sustainable tourism in the long term, with regard to their developments and their various impacts (social, environmental and economic) on those places.","PeriodicalId":414074,"journal":{"name":"Association of Arab Universities Journal of Engineering Sciences","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127399956","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experimental data fitted slightly best to the Langmuir isotherm model than to Freundlich and Temkin isotherm model. The experimental data proved that the adsorption kinetic of MB, MG, and MV could be described by a pseudo-second order model.

Commercial grade of magnetite (Fe3O4) with an average nanoparticle size of 50 nm was used. The effect of some factors such as initial pH of the solution (5-9), current density (5-25 mA/cm2), and magnetite dosage (0.4-2.5 gm) on the efficiency of the process were studied. The residual turbidity obtained by using electrocoagulation process alone was (7.47 NTU) from initial turbidity of (200 NU) at constant conditions of pH 6, current density 15 mA/cm2 and electrolysis time 20 min.
