Abstract
Nigerian Schools of Architecture face the various challenges of out-dated design, declining conditions, and capacity utilisation pressures. The effects of these conditions are threats to the academic performance of the students. The study aimed at investigating the impact the learning environment has on the academic performance of students of Architecture at Covenant University, Ota, Ogun State, Nigeria. This research made use of quantitative and qualitative research approach. Data was collected through a structured questionnaire, and the IBM SPSS (Statistical Package for Social Sciences) was used for analysis. Results show that the classroom environment has effects on students’ academic performance. This is due to their satisfaction and comfort in the learning environment. Findings also show that the comfort derived from facilities and physical components within the classroom affects their academic performance. Although the research findings have shown that the physical components of the classroom learning environment had no direct impact on the students’ academic performance, based on the research it is recommended that visual learning aid should be maximised. Also, the classroom facilities should be improved to encourage students to make use of their classrooms. Further, the physical components classroom environment affects but does not have a direct impact on students’ academic performance; however, the perception of students on these components should be explored to create a comfortable classroom environment.

AbstractVisual quality assessment plays a major role in determining the visual sustainability of the physical environment. Visual sustainability underscores the visual relationship between people and their environment. Several studies have been carried out on the subject of visual quality in architecture from other parts of the world. However, not much is seen on record in the Nigerian context. There are also concerns that there is a decline in the visual quality of university buildings. In the light of foregoing, it is essential to understand in detail the visual quality of university buildings not only from the perspective of built environment practitioners but also from the general public as potential users of the buildings. In this respect, the senate buildings of selected universities in Southwest Nigeria were selected for the study given the central role such buildings play in university administration and interaction with a variety of users. However, the senate building of Covenant University Ota is the focus of this paper. The study was aimed at identifying the architectural elements on the Covenant University Senate Building facade to understand public perception for future applications in architectural education, design, and overall visual sustainability. A cross-sectional survey was adopted for the study, and a stratified random sampling technique used in selecting respondents. In Total, 577 valid responses were collected from respondents in ten selected universities in Southwest Nigeria and analysed descriptively using frequencies, percentages, and mean score on the Statistical Package for Social Sciences (SPSS). Photograph of the Covenant University senate building façade was attached to the questionnaire to aid the visual assessment. Qualitative research involving the use of an interview guide preceded the survey research. The result from the study revealed that façade shape and height were perceived as the most interesting in the Covenant University senate building façade attractiveness. The study implied the need for equipping of designers on the perception of building design elements for adequate facade conceptualisation in designing. This, in essence, will enhance the attractiveness of the university senate building façade and also impact the entire campus visual sustainability.

Abstract
Youth unemployment is one of the most pressing issues confronting world leaders in the 21st century. Youth unemployment has negative implications for economic and social progress. In Nigeria, youth unemployment hit an all-time high of 55.4% in the third quarter of 2018. With almost all sectors been digitalised, digital skills become one of the most promising solutions to youth unemployment. It is a necessity for wage employment and in the creation of a personal business. However, anecdotal and empirical evidence shows that many youths lack the requisite skills for using digital technology productively. Hence, there is an increase in international and local efforts toward digital skills training for youths. This study reports the findings from a pilot digital skills training programme organised by the Double You Initiative in July 2019. It was based on a quantitative research approach with the use of an online questionnaire to obtain information from youths across Nigeria through a purposive sampling technique. The findings show that youths within the ages of 19 and 24 will likely subscribe more to digital skills training than any other age group. Also, undergraduate students are more interested in digital skills training, and the most common digital skill preference among youths is digital marketing. The lessons from the digital skills training reported in this paper can be useful in enhancing the preparedness of stakeholders towards the provision of digital skills training that will promote decent jobs for youths in Nigeria.

Abstract
In this paper, experimental analysis was carried out on a vapour compression system by varying the parallel tube condenser fins spacing under the same atmospheric condition in a selected Refrigeration and Air-conditioning laboratory to examine the performance characteristics of the refrigeration system. The fins spacing were 2, 4 and 6 mm using Liquefied petroleum gas (LPG) as working fluid with a mixture proportion of 17.2% isobutene, 56.4% butane, 24.4% propane. The result shows that the coefficient of performance of the system when working with condenser fins spacing of 2 mm was 28.8 and 35.9% higher compared to when the system worked with the fins spacing of 4 and 6 mm respectively. Energy consumed by the single hermetic compressor when the system worked with condenser fins spacing of 2 mm reduced by 16.4 and 18.7% compared to when the refrigerator worked with fins spacing of 4 and 6 mm respectively. The pull down time of the cooling system was attained in 2 hours 45 minute with minimum evaporator temperature of -13 °C while working with 30 g mass charge of LPG.

Abstract
Approaches towards public housing has been noted as Government-sponsored over time, the government have been accorded the responsibility of provision of safe, secure, sanitary, accessible and affordable housing for its citizens, both for low, medium and high incomes. Also in the fulfilment of the United Nations Sustainable Development Goals (SDGs), Goal 11; which seeks to make towns, cities and settlements an inclusive habitation that is safe, resilient and sustainable for all categories of people by the year 2030. However, due to various limiting factors, the government have run short of meeting this expectation and in order to bridge this gap, it has brought about the Private-Public Partnership (PPP) schemes to meeting mass housing provision. However, the success of Public-Private Partnership is dependent on certain socio-economic variations. This study assessed the residential satisfaction amongst residents of selected two public-private partnership housing estates in Lagos State, Nigeria. With a view to understanding the performance of the estates in meeting residents housing needs. This is done by identify the socio-economic and demographic characteristics of residents, examining the physical characteristics of housing units in the PPP housing estates and identifying the factors that influence occupants’ satisfaction with the PPP housing estates. The data were analysed using descriptive statistics and categorical regression analysis. The result showed that the housing situations are generally satisfactory to the residents. The residents were mostly satisfied with their housing unit features, followed by their neighborhood environment and least satisfied with the maintenance practices. The study revealed that the residents socio-economic characteristic and demographic is the most significantly predictor to the residents level of satisfaction. The study concluded that satisfaction derived by residents of the PPP housing estates studied can be improved by provision of better housing maintenance practices and effective infrastructures and services.

Abstract
The ubiquitous demand for thermal energy in domestic and industrial applications, necessitates the need that heating systems, are effectively insulated, portable and occupy less space. This research focuses on the design and fabrication of a portable crucible for insulating a thermal energy storage system operating at high temperature. The insulating properties of the crucible were also investigated. Two ceramic crucibles, comprising of kaolin, and a mixture of kaolin and sand, were fabricated using the parameters obtained from simulation. When subjected to thermal treatment, the crucible comprising of kaolin and sand structurally failed at 75 °C. However, the crucible comprising of only kaolin remained stable and attained steady state at a temperature of 200 °C. The heating and cooling temperature curves of the kaolin crucibles were plotted and the estimated thermal conductivity of the kaolin crucible was 0.09 W/mK at 200 °C; this is in good agreement with theoretical values of kaolin which range from 0.03 to 0.3 W/mK. The computed thermal diffusivity is 4.9x10-8 m2/s, which is much lower when compared with the thermal diffusivity of insulating materials like polystyrene, glass fibre and rock wool. Thus, the rate at which heat diffuses through the crucible is low, making it suitable for insulating a thermal energy storage material operating at 800 °C. The results of this study will facilitate an efficient way of transporting stored thermal energy in portable insulating containers.

Abstract
Anthocynanins and anthocyanidins have been widely applied in various fields such as sensitizers in dye sensitized solar cells (DSSCs). DSSCs provide an alternative to the present photovoltaic technology due to its numerous advantages such as flexibility, easy fabrication, semitransparency and colour tunability. In this study, comparative analysis between crude and purified extracts obtained from withered leaves and flowers of Euphorbia mili (crown of thorns) as organic sensitisers in DSSCs. The optical and photovoltaic properties of the extracts was examined using an ultraviolet (UV) spectroscope and solar simulator respectively. There were observed shifts in the wavelength of the absorptions at (350 – 380 nm) for both extracts (crude and purified). The results from the photovoltaic parameters indicate an improved power conversion efficiency (PCE) for the crude extract of the flower at 2.72%.

Abstract
In major cities in Nigeria, the current modes of transportation are generally chaotic and unsustainable. We therefore have to rethink how to adopt the seamless integration of sustainable transportation alternatives. Poor maintenance is one of the factors adduced to be responsible for the current deteriorated state of mobility corridors and the existing road infrastructure. Overpopulation and increasing socio-economic activities of Festac Town exerts undue pressure on the infrastructure, thereby accelerating deterioration. The study is underpinned by Eco-mobility principles. This study is aimed at assessing the eco-mobility approach for a sustainable neighbourhood road infrastructure within a mixed-use community. Developing a sustainable mobility strategies that brings the neighborhood streets back to the people is an objective which this study pursue. A multi-staged sampling technique was adopted for the study. On-site qualitative approach was majorly employed through the interviews conducted assessing the major mobility corridors and streets from 1st to 7th avenues. A sample frame of 15 major roads with outdoor open spaces along the selected roads all within the selected avenues and major street roads. The instruments for data collection were oral interviews and personal/physical observations. The activity profiles, locational data and geospatial coordinates of each avenue were imported into ArcGIS (Version 10.5, ESRI) for various land-use analysis. The sustainable eco-mobility strategies will reduce transportation impacts, create civilized streets that meets environmental design standards of commuter’s safety and comfort that are compatible with the unique urban structure and culture of metropolitan Lagos. This study evaluated the issues relating to sustainable eco-mobility, the connection between climate change and transportation systems, the impact of urban mobility on public health and wellbeing. It further outlined policy frameworks to be considered in other to have a sustainable neighbourhood streets mobility networks within a mixed-use community.

Published: March 2021

AbstractThe improvisation of renewable energy sources is of global concern as there is foresight in the depletion of fossil fuels. This is because there is dependence on energy fuel consumers over time and the detriment on the biotic and abiotic component of the environment is alarming. The need for an alternate source of energy source is imperative. Several options have been considered by the scientific community, especially biofuels which hinges primarily on the type of biomass. Agro waste is most considered because of its abundance but it is competed for as feeding purposes in humans and animals. However, Lignocellulose is being utilized recently. The preliminary step in the conversion of the lignocellulose (pre-treatment) stage is the most challenging which is presented in three major methods; physical, chemical, and biological treatment. This review assessed its sustainability and the limitations of each of these methods. The biological pre-treatment poses to be a cost-effective method with a low yield of products. These shortcomings could however be managed by redesigning the procedure to include a partial chemical pre-treatment, optimization of the process parameters such as pressure, temperature, and genetic manipulation of microorganisms of choice.

Abstract
At first glance, misery seems unquantifiable but has been established to be an aggregation of unemployment and inflation. Nigeria is in a pitiable condition as she is ranked the 6th most miserable country in the world. This study aims to ascertain the effect of economic growth on Misery in Nigeria, that is, to determine whether economic growth rate has strengthened or weakened the misery of Nigerians. This study adopts Autoregressive Distributed Lag (ARDL) model because it considers policy lags of economic phenomena and allows combined order of integrations. The study finds an inverse nexus between economic growth and misery. Hence, recommendations were made in form of measures to ensure the need for economic growth to increase at faster and higher pace to combat high misery levels in Nigeria.
