Öğe Architecture and Contextualism in Mosque Design as a Multi-faith and Community Friendly Place(E-IPH LTD UK, THE LEADMILL, 6 LEADMILL RD, PO BOX STUDIO 7, SHEFFIELD, S1 4SE, ENGLAND, 2021) Samsudin, Intan Liana; Rabu, Zurinda Mat; Mazlan, Ida Marlina; Dodo, Yakubu AminuThe research aims to outline the design strategy for a mosque as a third place to promote an inclusive community friendly place. The research employs a qualitative case study methodology through observation and interview. The findings reveal that an inclusive mosque architecture can be enhanced based on the following design strategies: scale intimacy, ease of previewing, minimalist and adaptive building, space ambient, and impermanence landscaping character. Above all, the relationship between design, function, space and programming should be reestablished to infuse the mosque's inclusion for the benefit of all faiths, particularly the community.Öğe Assessment on Accuracy of Design Science Research (DSR) Framework as a Daylighting Measurement Tool for Islamic Religious School(E-IPH LTD UK, THE LEADMILL, 6 LEADMILL RD, PO BOX STUDIO 7, SHEFFIELD, S1 4SE, ENGLAND, 2021) Yazit, Raja Nur Syaheeza Raja Mohd; Husini, Elina Mohd; Khamis, Mohd Khedzir; Dodo, Yakubu AminuDaylight efficiency correlates to window design. Standards and guidelines recommended 20% window to floor ratio (WFR) at 800mm to 900mm windowsill height for classrooms, where it should provide the recommended illuminance level between 300 lx to 500 lx measured at working plane height (WPH) between 800mm to 900mm. Instead, Islamic religious schools use ‘rehal’ at 300mm WPH. Since that the WPH is lower, the measured illuminance level is at different intensity. This paper assesses the accuracy of Design Science Research (DSR) methodology framework adaptation in measuring and designing daylight consideration in Islamic religious schools that uses lower working plane height.Öğe Built environment transformation in Nigeria: the effects of a regenerative framework(Taylor & Francis Ltd, 2024) Agboola, Oluwagbemiga Paul; Alotaibi, Badr Saad; Dodo, Yakubu Aminu; Abuhussain, Mohammed Awad; Abuhussain, MaherThe promise of a healthier, more comfortable, and more productive way of life has fueled a rapid technological transition, and a regenerative built environment has emerged as the tagline to denote the recent sustainable development. In the built environment, the regenerative paradigm has emerged as a transformative approach that goes beyond mere sustainability, aiming to restore, renew, and enhance the ecosystems affected by human activities. However, the concept of the regenerative paradigm and its potential to foster sustainable development has been understudied in recent time. Therefore, this paper explores how we can transform the built environment in the face of the present impacts of climate change using a new regenerative paradigm concept. The objectives of the study are: (i) to explore the predictors of climate change, (ii) to determine the negative impacts of environmental issues on inhabitants' health, and (iii) to explore adaptive climate change strategies for Nigeria's regenerative built environment. The study sample consisted of 235 stratified respondents' opinions from within the built environment in southwestern Nigeria collected via a self-administered questionnaire. The collected quantitative data was analysed using SPSS (version 22) logistic regression analysis. The major results of the analysis revealed: (i) the ten most important predictors of climate change indicators, (ii) the existence of negative consequences of the impacts of climate change on inhabitants' health in southwestern regions of Nigeria, and (iii) a significant (p & LE; 0.05) in all regenerative factors: planting native species has the highest & beta; coefficient of 0.499, followed by the biophilic approach (0.494), the establishment of a city's tree canopy (0.467), the creation of a green functional green space (0.436), the use of smart landscaping techniques (0.388), and the development of a healthy watershed (0.314). This indicates that to have a regenerative built environment it is essential to create a functional green space, plant native species, establish a city's tree canopy, create a healthy watershed, and render a biophilic approach. The study's recommendations include urgent action to integrate climate change interventions into the decision-making processes, initiatives, and development plans of the Nigerian government. This integration should prioritize sustainable practices within the built environment, considering the regenerative paradigm's potential to address climate change impact effectively.Öğe Carbon dioxide-assisted Torrefaction of Maize Cobs by Thermogravimetry: Product Yield and Energy Recovery Potentials(VASYL STEFANYK PRECARPATHIAN NATL UNIV, VUL SHEVCHENKA 57, IVANO-FRANKIVSK 76018, UKRAINE, 2022) Nyakuma, Bemgba Bevan; Ajibade, Samuel-Soma M.; Adebayo, Victor B.; Alkali, Habib; Otitolaiye, Victor Olabode; Audu, Jemilatu Omuwa; Bashir, Faizah Mohammed; Dodo, Yakubu Aminu; Mahmoud, Abubakar Sadiq; Oladokun, OlagokeThe objective of this study is to examine the potential product yields and energy recovery of maize cobs (MC) through carbon dioxide-assisted torrefaction using thermogravimetric analysis (TGA). The CO2-assisted torrefaction of MC was performed from 240 °C to 300 °C (? 30 °C) for the residence time of 30 minutes based on the selected non-isothermal/isothermal heating programme of the TGA. Furthermore, the physicochemical, microstructure and mineral characteristics of MC were examined. The results showed that the CO2-torrefaction of MC resulted in mass loss (ML) ranging from 18.45% to 55.17%, which resulted in the mass yield (MY) ranging from 81.55% to 44.83%. The HHV of the solid product was in the range from 22.55 MJ/kg to 26 MJ/kg, which indicates the CO2-torrefaction process enhanced the energy content of MC by 40% – 60%. In conclusion, the findings showed that the CO2 torrefaction is a practical, sustainable, and cost-effective approach for the valorisation of MC into a clean solid biofuel for enhanced energy recovery.Öğe Climate Change Adaptation and Mitigation in Sub-Saharan African Countries(Springer, 2021) Adenuga, Kayode I.; Mahmoud, Abubakar Sadiq; Dodo, Yakubu Aminu; Albert, Moutlen; Kori, Said Alkali; Danlami, Nusa JibrilThe impact of climate change and global warming is high on agriculture, food security, quality of life, human health, economic growth, and development in sub-Saharan African countries. Thus, there are ongoing global discussions on climate change adaptation and mitigation including the Kyoto Protocol; an international treaty which extends the 1992 United Nations Framework Convention on Climate Change (UNFCCC) that commits state parties to reduce greenhouse gas emissions caused by global warming, the 2012 Doha Amendment to the Kyoto Protocol, United Nations Development Programme climate change portfolio, United Nations Educational Scientific and Cultural Organization climate change awareness program, United Nations Environment Programme (UNEP) and other bodies efforts to reduce climate pollutants globally, Africa in particular. However, despite these interventions, there is little scholarly information discussing the extent to which the region’s vulnerability to climate change on its economies and growing populations is addressed. Thus, this review paper examines the impacts of climate change and global warming in sub-Saharan African countries and strategies adopted to mitigate the effects on its environments and economy. © 2021, Springer Nature Switzerland AG.Öğe Enhancing Najran’s sustainable smart city development in the face of urbanization challenges in Saudi- Arabia(TAYLOR & FRANCIS LTD, 2-4 PARK SQUARE, MILTON PARK, ABINGDON OR14 4RN, OXON, ENGLAND, 2024) Alotaibi, Badr Saad; Elnaklah, Rana; Agboola, Oluwagbemiga Paul; Abuhussain, Mohammed Awad; Tunay, Mustafa; Dodo, Yakubu Aminu; Maghrabi, Ammar; Alyami, ManaThis research offers valuable perspectives on the nexus between urbanization and the smart environment within the Najran city, Saudi Arabian context. Najran City, with its diverse districts and evolving urban landscape, is at the forefront of adopting advanced technologies and participatory governance models to create a resilient, environmentally conscious, and sustainable urban environment, likewise positioning itself as a model of smart urban development but is also fostering an innovation-driven community equipped to address the difficulties and exploit the prospects given by the 21st century. The study systematically analyzes the multifaceted factors of smart city variables in Saudi Arabia and their direct impact on urban sustainability through extensive quantitative investigations. This study reveals the positive correlations between smart city attributes, on the attainment of urban sustainability. In order words, the smart city’s attributes such as IoT (Internet of Things) devices, smart infrastructure, and data-driven solutions are linked to the creation of a resilient urban environment in the face of urbanization and sustainability challenges. On the other hand, the study noted that the integration of smart technologies might lead to unintended consequences in urban planning. For example, an overemphasis on technology may overshadow human-centric approaches, which might potentially affect the community well-being and social cohesion. Study’s insights provide policymakers, urban planners, and players with an indepth knowledge of the pathways to harness smart city attributes for sustainable Najran urban development. The implications of this research extend beyond the borders of Saudi Arabia, serving as a valuable reference for regions worldwide grappling with similar urbanization and sustainability challenges in the 21st century. By harnessing the potential of smart cities, Saudi Arabia and other nations can pave the way for greener, more resilient urban futures.Öğe The influence of information and communication technology (ICT) on stakeholders' involvement and smart urban sustainability(Elsevier Ltd, 2023) Agboola, Oluwagbemiga Paul; Bashir, Faizah Mohammed; Dodo, Yakubu Aminu; Mohamed, Mohamed Ahmed Said; Alsadun, Ibtihaj Saad RashedIt is impossible to overstate the role that smart cities and the building resilience strategy play in the movement toward environmental sustainability, particularly in industrialized and developing nations. There has been a rise in the use of efficient systems to enhance built environment control and accomplish infrastructure development projects, and for this to be successful, countries around the globe, including Nigeria, need robust smart cities and buildings. Few researchers have looked at how smart cities and building projects might improve the sustainability practices of Nigeria's built environment in the context of environmental issues. The major research aim of this study is to investigate the role of Information and Communication Technology (ICT) in advancing urban sustainability in the context of Lagos, Nigeria, amidst the city's rapid population growth and the implementation of smart city projects. The study's research questions include the following: First, How can information and communication technology (ICT) be leveraged to support the development of urban sustainability? Secondly, what is the impact of ICT on stakeholders' involvement and participation in urban sustainability? Thirdly, how can stakeholders' involvement and participation impact urban sustainability? Structural equation modeling using partial least squares (SmartPLS 3.0 Edition) as an analysis tool was used to assess the suggested model and the empirical study results in support of all the hypothesized associations. Results revealed that Information and Communication Technology (ICT) is positively associated with smart urban sustainability. Also, a positive and significant influence of ICT on consolidating stakeholder involvement and participation is paramount. Lastly, smart city and building initiatives have the potential to significantly improve urban sustainability. The implication of the study enables the possibility to optimize the impact of an ICT-based urban environment, thereby creating sustainable and resilient communities that meet the needs and priorities of all members of society. © 2023 The Author(s)Öğe Key Performance Indicators (KPIs) to Promote Building Developers Safety Performance in the Construction Industry(OMNIASCIENCE, TERRASSA, BARCELONA 00000, SPAIN, 2020) Mahmoud, Abubakar Sadiq; Ahmad, Mohd Hamdan; Yatim, Yahya Mohd; Dodo, Yakubu AminuPurpose: The aim of this study is to establish key performance indicators (KPIs) that can be deployed in the evaluation and promotion of safety performance of building developer’s in Nigeria. Design/methodology/approach: A thorough review of the literature was performed to generally identify sets of KPIs used to evaluate the safety performances of building developer’s during construction. Interviews and focus group discussions were conducted with eleven (11) subject matter experts and professionals to ensure inclusion, validation and clarity of the indicators and to further provide agreement/disagreement, and importance ratings for the identified KPIs. The KPIs was grouped into appropriate categories, keeping out redundant KPIs, and ensuring KPIs are clear and measurable. The Relative Importance Index (RII) and Mean values were computed. Findings: Results from the study consist of 137 KPIs, grouped into 9 categories including: Planning, design and procurement, communication on & maintenance of effective safety behaviour, construction safety policy, construction safety personnel, management effort and support, safety training and enlightenment, administration of safety processes, investigation and reporting of accidents, and rewards and sanctions for project stakeholders. These KPIs were observed to be at different levels of importance from the respondents. The following KPIs were considered based on their extreme importance judging from the respective RII values: communicating safety requirements to designer (98.18%), safety performance set as part of contractor selection criterion (96.36%), availability and accessibility of the relevant insurance policies (98.18%) and appropriate issuance of motivational directives by the top management (100%). Originality/value: Many studies have been done in the past where KPIs as it relates to construction safety were identified. However, the specificity of these KPIs to countries other than Nigeria requires similar research be conducted to identify building developer safety performance KPIs for the Nigerian construction industry.Öğe Mechanical and Fresh Properties of Sustainable Kenaf Fibrous Concrete Incorporating Sorghum Husk Ash(Univ Tun Hussein Onn Malaysia, 2021) Ogunbode, Ezekiel Babatunde; Dodo, Yakubu Aminu; Moveh, SamuelThis article describes the findings of an experimental investigation on the performance of concrete using Kenaf Fiber (KF) and Sorghum Husk Ash (SHA) (CEM 1). To characterised the SHA (EDS), microstructural studies such as X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray fluorescence (XRF), and Energy-dispersive X-ray spectroscopy were performed. CEM 1 was used with the KBF (length, L = 50 mm) and five volume fractions ranging from 0 to 1.0 percent (= 0.25 percent). Following that, five concrete mixtures were cast with 10 percent SHA as a substitute for CEM 1. The samples were cured in water and their characteristics were evaluated in both the fresh and hardened stages. In new concrete, the use of Kenaf fibre and SHA lowered slump values while increased VeBe time. When Kenaf fibre was added to either CEM 1 or SHA concrete mixes, it resulted in a good interaction with high tensile and flexural strengths, as well as increased concrete ductility and crack dispersion. When 0.5 percent Kenaf Fibre was added to dry concrete at the age of 56 days, it resulted in the largest increase in tensile and flexural strengths. The research found that utilising KF and SHA to manufacture sustainable green concrete is both technologically and environmentally viable.Öğe Park visitation in the context of Khartoum town(INST ADVANCED SCIENCE EXTENSION, PO BOX 23-31, TAIPEI 00000, TAIWAN, 2021) Ibrahim, Ahmed Osman; Said, Mohamed Ahmed; Dodo, Yakubu Aminu; Bashir, Faizah Mohammed; Dano, Umar LawalParks improve people's physical and mental well-being, strengthen communities, and make towns and neighborhoods more appealing places to live and work. Many reasons discourage frequent park visitations, such as poor park characteristics, poor management system, and the lack of programs to encourage park visitation. Participation in different outdoor activities has become a necessity for many people nowadays. However, many residents are not engaged in recreational activities in Khartoum, making parks an important element. Therefore, the study aimed at investigating parks characteristics and different patterns of users based on societal needs. The study concentrates on the residents' characteristics such as age, gender, income, education level; these characteristics are tested against park visitation patterns such as type of visitation, the best day for visitation, and visit frequency. A two hundred and fifty (250) participant questionnaire survey was carried out in Al Tifl Park to assess the park's visitation pattern based on the purposive sampling technique. The result shows that most of the visitation patterns were not frequent regardless of the visitors' characteristics. It proves that the visitation pattern was not based on the visitors' characteristics but rather on the park characteristics. The study recommends that the park's features be redesigned based on user affinity to improve visitation, visitor benefits, and income generation.Öğe Strengthening Resilient Built Environments through Human Social Capital: A Path to Post-COVID-19 Recovery(Mdpi, 2023) Agboola, Oluwagbemiga Paul; Nia, Hourakhsh Ahmad; Dodo, Yakubu AminuThere are strong indications that the built environment has had a great influence on the course of the COVID-19 pandemic and the post-disaster recovery. The COVID-19 pandemic has adversely affected both human and global development, while efforts to combat this menace call for an integrated human social capital index. This research seeks to enhance understanding of how the built environment can be enhanced through resilience against the backdrop of the COVID-19 pandemic. This study aims to investigate the impact of a resilient built environment on increasing resilience in the aftermath of the COVID-19 pandemic in Nigeria. The quantitative studies test the impact of four built environment resilience indices (built environment capital, disaster management indices, awareness of the COVID-19 pandemic, and built environment adaptive strategies) on human social capital and COVID-19 pandemic indices. This study reveals the role of human social capital in achieving a resilient built environment in the wake of the COVID-19 pandemic in Nigeria. Built environment capital, disaster management indices, and awareness of COVID-19 also indirectly affect the COVID-19 pandemic indices through human social capital. This study's implications are useful for post-COVID-19 recovery, which is important for future planning of the built environment in Nigeria.Öğe Thermogravimetric Study of Maize Cob Carbonization for Bioenergy Recovery: Product Yield Estimation and Bio-Energy Potentials(Slovnaft VURUP a.s, 2021) Otitolaiye, Victor Olabode; Ojomoh, Victor Kayode; Mahmoud, Abubakar Sadiq; Bashir, Faizah Mohammed; Audu, Jemilatu Omuwa; Dodo, Yakubu AminuThe study investigated the bulk fuel, microstructure, morphological, mineral, and functional group characteristics of maize cobs (MC) along with carbonization through thermogravimetric analysis (TGA) for potential energy recovery. To the best of the authors’ knowledge, this is the first study on the micro-scale analysis of the fuel properties and bioenergy recovery potential of MC in the scientific literature. The results showed that MC contains high carbon, hydrogen, oxygen, volatile matter and fixed carbon but low moisture, and ash contents. The functional group (FTIR) analysis revealed MC contains alcohol, ester, and carbonyl functional groups in its chemical structure, which could be attributed to the lignocellulose components of biomass. The analysis of MC microstructure and morphology showed a rough yet compact surface comprising fibres. The TGA carbonisation process revealed MC experienced significant mass loss (ML) ranging from 73–76%, whereas the residual mass or mass yield (RM or MY) was from 23.6–27.2% with increasing carbonisation temperatures from 450–650°C. Furthermore, the findings indicated that the optimal temperature for carbonization of MC is 550°C, based on the conditions examined in this study. The HHV of the solid MY ranged from 26.66 – 26.99 MJ/kg, whereas the energy yield (DE) was 95.42 – 95.63%, and energy density (DE) 3.52 – 4.04. The findings indicate that while the HHV and EY increased, the MY and EY decreased with increasing carbonisation temperatures. In general, the study demonstrated that MC is a potentially suitable raw material or biomass feedstock for the sustainable recovery of bioenergy through carbonization. © 2021.
