Abstract. Adsorption of congo red on bentonite was studied kinetics and thermodynamically. Bentonite was physically activated at various temperatures and characterized using X-ray, and infrared. By increasing thermal temperature activation up to 500 o C can decrease the montmorillonite fraction with decreasing the peak was observed. The kinetic of adsorption suggests that the interaction of congo red-bentonite could be best represented by the first-order kinetics of Langmuir-Hinshelwood model. The adsorption process was exothermic with H in the range -4.43 to -9.76 kJ.mol -1 accompanied by increase in Gibbs energy. All results have shown that bentonite after physical activation could be used as an adsorbent for congo red adsorption.

The research study investigates the effectiveness of solar management techniques on the outdoor thermal comfort in hot, arid climates within the context of higher educational facilities. Qatar University in Doha, State of Qatar, is establishing the contextual unit of analysis as it provides a case study for urban planning and design within an educational environment. The campus has dynamic outdoor spaces that have been treated using urban strategies and techniques to create the most desirable environment for its vast range of users including students, faculty and staff members. The aim of the study is to assess the effectiveness of the current solar management techniques at Qatar University campus based on user's satisfaction. Therefore, the focused scope of analysis is targeting the shading devices that are found in the campus, which has been generally categorized as pedestrian shaded pathways with detached canopies and car parking shading structures. The thesis targets the following question: does the current shading devices on campus provide a satisfactory experience for users in addition to encouraging walkability and better utilization of outdoor spaces? By investigating the effectiveness of solar management techniques, it is possible to optimize the use of the current shading devices by relating their effectiveness to users' satisfaction and thermal comfort. Based on the methodology of survey analysis, a sample of fifty questionnaires has been collected and analyzed with reference to the existing users of the campus. The survey questionnaire is reinforced by further direct impressionistic observation as a verifying methodology. Results obtained from both methods of analysis are indicating the ineffectiveness of the current solar management techniques represented by shading devices in the campus of Qatar University, however supported by numerous applicable suggestions for improvement.

“…Over the past decade, Qatar, recognized as 'one of the most important producers and exporters of Liquefied Natural Gas (LNG) in the world' , has witnessed a wealth, which has contributed to a rapid and significant urban growth and/or to a new form of urbanism. In turn, this has prompted the development of various new forms of urban typologies, such as iconic skyscrapers, waterfront glass towerhotels, cultural and educational urban facilities [15].…”

“…Major changes to the built environment of Doha have been caused by the construction of infrastructural and large-scale urban and architectural projects, planned and currently under construction for the foreseen 2022's World Cup. Also, Qatar is currently making large investments in urban public transit systems (for example the Doha metro, the Lusail LRT (light rail transit) and BRT (bus rapid transit)), which will contribute to further developments around/along the major train stations [14][15][16][17].…”

Scholars and researchers, who investigate the extent to which spatial form and livability are mutually interconnected, stress that the built environment provides the space for the enhancement of social interactions, which in turn have a deep impact on the level of livability of cities. Namely, in relation to this relationship, to which extent the built environment of (1) the contemporary business district of 'West Bay' and (2) of the heritage site of the 'Souq Waqif' in Doha contributes to the enhancement of social interactions and/or livability has not been comparatively investigated yet. This study aims at investigating how the spatial form of the two selected precincts contributes to create a livable environment. The analysis indicates that while West Bay's contemporary built environment contributes to the image of Doha as a modern city, the traditional settlement of the Souq Waqif contributes to the formation of a sense of community, increase occasions for social interactions, enhance livability and finally consolidate cultural identity.
