This book seeks to address the key challenges and opportunities of "future cities" embracing novel approaches and grounded technologies in pursuing a vision for smart, inclusive cities. The objective of this book is to discuss multiple areas at the local, national, and international levels and how these challenges can hinder the development objectives planned to be achieved by the cities of the future. The chapters featured in this collection were presented at the 6th Memaryat International Conference (MIC 2022), held at the Effat University, Jeddah. MICs objective is to build bridges between science, technology, and innovation, seen as the key levers of attaining the SDGs. This book provides the most innovative ideas presented at the conference to address the key manifestation of "future cities" to embrace novel approaches and grounded technologies in the pursue of a vision for smart inclusive cities. It thus represents a platform for diverse contributions from academics and practitioners to present their different perspectives addressed theoretically as well as in practice concerning the challenges and opportunities of future cities. This includes contributions from decision-makers, architects, urban planners, urban designers, entrepreneurs, and educators to stimulate discussion covering the latest on the challenges and opportunities for better future cities in the different domains of architecture, building science and technology, environmental design, mobility & infrastructure, urban design & landscape, housing & real estate developments, urban planning, governance, socio-cultural & economic development, community engagement, tourism and heritage revitalization.

AbstractPetroleum oil leakage and industrial oily waste on the water surface are sustainable pollutions. The removal process by eco-friendly adsorbents is a critical challenge. It also requires sustainable treatment. The natural hydrophobic material such as abietic acid, boswellic acid, and chitosan was added to magnetite nanoparticles with different concentrations of 10, 15, and 20% on its surface. The magnetite acquires partially hydrophobic properties. The prepared natural adsorbents were analyzed by employing wide-angle X-ray diffraction (WAXD), vibrating sample magnetometer (VSM), Fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM), particle size and zeta potential, and contact angle measurements. Chitosan adsorbs at the outer surface of magnetite nanoparticles while boswellic and abietic absorb in bulk. All prepared adsorbents are effective in adsorbing waste oil from the water surface. The contact angle of MB20 (magnetite/20 percent boswellic) is greater than that of MA20 and MC20 (magnetite/20% abietic or chitosan, respectively), indicating that it has more hydrophobic characteristics. The oil removal efficiency and adsorption capacity of MB20 are the highest values 57.6%, and 24 g/g, respectively. All eco-friendly adsorbents are nontoxic with low-cost production and are used many times.

Background: A large number of mentally ill patients prefer to visit non-medical practitioners such as traditional healers because of the confidence in the system, affordability and accessibility of the service. This may lead to delay in seeking psychiatric services and has prognostic impact. Aim: To assess the rate of bipolar affective disorder (BAD) patients seeking traditional healers, the sociodemographic and clinical correlates of those patients. Methods: We assessed 350 patients with BAD after confirmation of diagnosis with Structured Clinical Interview for DSM-IV Axis I Disorder (SCID-I) research version and assessment of functioning with Global Assessment of Functioning scale. They were assessed for percent, rate and timing of seeking traditional healers. Results: In all, 40.8% sought traditional healers, with 34.9% more than four times. Of those, 62.2% were before seeking psychiatric services and 37.8% after. Lower educational level, less impairment of functioning and presence of hallucinations were significant correlates. Conclusion: This study shows that most of the patients suffering from mental illness prefer to approach faith healers first, which may delay entry to psychiatric care and thereby negatively impact the prognosis of BAD. This highlights the importance of mental health education and developing a positive collaborative relationship with traditional healers.
