Assessing Trends of Vehicle Ownership and Use Among Tertiary Students in Kwame Nkrumah University of Science and Technology Campus, Ghana

The study aims to assess trends of car ownership and usage among tertiary students on campus, with an emphasis on Kwame Nkrumah University of Science and Technology (KNUST). The research design employed in this study was descriptive survey, aiming to gather information from a sample population through their responses to specific questions. Data analysis was conducted using descriptive statistics, summarizing the responses quantitatively through bar charts, pie charts, frequencies, percentages as well as means and tables, created using Microsoft Excel. The results revealed that, a majority (70 percent) of the cars being used by students on the KNUST campus are owned by Ghanaian students with foreign students making up the minority of this number. The major challenges faced by students who own or use vehicles on campus are a lack of filling stations on and around campus, lack of student parking lots, and excess traffic. From the findings, it can be concluded that, students' psychological make-up is a major determinant of vehicle ownership among students. Moreover, the findings further revealed that most of the students who have vehicles on the campus exhibit or develop mostly negative habits after vehicle ownership and this in the long run may have negative effects on academic performance which is the sole purpose of being on campus. The study provides insights into the environmental and health impacts of increased vehicle use on university campuses, offering valuable insights for policy decisions, future research, and campus management, thereby enhancing student mobility.

Phytoremediation of Cr(VI)-rich wastewater using Water Hyacinth, Water Lettuce and Duckweed

Chromium(VI) contamination is carcinogenic and largely anthropogenic, stemming from specific industries. With Bangladesh experiencing rapid industrialization, the increasing number of industries necessitates an economic and sustainable secondary treatment process to maintain acceptable chromium levels. Phytoremediation, an environmentally friendly biochemical technique, has been extensively researched, particularly in the context of constructed wetlands. However, due to land scarcity and legal issues a constructed wetland is not the most viable option. In this study, three native aquatic plants—Eichhornia crassipes (Water Hyacinth), Pistia stratiotes (Water Lettuce), and Lemna minor (Duckweed)—were chosen to evaluate their effectiveness in removing chromium from wastewater. These plants underwent testing with five different chromium concentrations (1 mg/L, 2 mg/L, 3 mg/L, 4 mg/L, 5 mg/L) and two pH values (6 and 8) using natural ditch water as the feed solution. All the experiments were performed for 7 days in duplicate, along with a control experiment of chromium without plants. The study was conducted at Shahjalal University of Science and Technology campus, Bangladesh, from May 25 to June 1, 2023. Atomic Absorption Spectrometer was employed to measure Cr(VI) concentration, revealing average chromium removal rates of 29.4%, 81.1%, and 81.5% for Eichhornia crassipes, Pistia stratiotes, and Lemna minor, respectively, after seven days. Notably, on day three, Lemna minor exhibited the highest average removal efficiency at 84.7%.

Investigating carbon footprints of the Malawi University of Science and Technology

Background: Increasing greenhouse gasses concentration in the atmosphere is perturbing the environment to cause grievous global warming and associated consequences. Following the rule that only measurable is manageable, mensuration of greenhouse gas intensiveness of different products, bodies, and processes is going on worldwide, expressed as their carbon footprints (CF). Methods: The methodologies for carbon footprint calculations are still evolving and it is emerging as an important tool for greenhouse gas management. The purpose of this paper was to determine the CF of the Malawi University of Science and Technology (MUST) campus and identify the stressors. The greenhouse gasses (GHG) protocol separates emissions into three scopes which include scope 1 of direct emissions, scope 2 which is indirect emissions, and scope 3 of other indirect emissions. Findings: The estimation of CF from transportation measured 930670.2 kgCO2e, and from electricity measured 2824243.2 kgCO2e while from the use of charcoal fuel measured 30804 kgCO2e. Results showed that emissions generated by gen-sets and transportation produced the highest contribution of 669124.8 kgCO2e and 238991.4 kgCO2e respectively to the MUST campus in the year 2018-2019 as compared to previous years (2015-2017). Conclusion: The study strongly suggested that for the whole 5 years period the use of gen-sets in the campus was the main stressor and this was due to frequent blackouts. Second was transport and as the university grows, the demand for transportation will also increase hence more emissions from transport. Therefore the study recommends that the university should be more considerate of these carbon dioxide sources so as it is trying to meet its needs and demand from these activities, it should also consider reducing the carbon footprint of the campus. Novelty/Originality of this Study: In a pioneering effort for Malawian higher education institutions, this study quantifies the carbon footprint of the Malawi University of Science and Technology campus, paving the way for targeted greenhouse gas management strategies in academic settings.

Examining UV Radiation Patterns in Relation to Particulate Matter and Atmospheric Conditions in Arid, Unclouded Skies

This study investigates the influences of air temperature (T), relative humidity (RH), wind speed (WS), clearance index (KT), particulate matter (PM) concentrations (PM10 and PM2.5), and aerosol optical depth (AOD) on ultraviolet (UV) radiation during clear skies in Riyadh, central Saudi Arabia. The observational dataset utilized in this study comprises global solar radiation (G), UVA radiation, AOD measurements, and PM concentrations. The data were collected from 2014 to 2015 at the King Abdulaziz City for Science and Technology (KACST) campus in Riyadh. Regression analyses were conducted to investigate the relationships between UV radiation and the considered variables. The methodology is based on the least square method and associated statistical tests. The findings of this study provide valuable insights into the impacts of meteorological variables and aerosols on UV radiation, contributing to the understanding of environmental and industrial applications in the Arabian Peninsula. The analyses showed that the strengths and magnitudes differed from one variable to another. No significant correlations between UVA radiation (315–400 nm) and hourly and daily values of PM2.5 were found. Moreover, no significant correlations were seen between daily values of the UVA radiation and RH and between the UVB (280–315 nm) and PM10. The rest of the correlations (between UV radiation and the PM10 and meteorological variables) were found to be significant. While WS, the ratio of the PM concentrations (PM2.5/PM10), KT, and T exhibited positive correlations with UV radiation, the rest of the variables had anti-correlations with UV radiation. The influences of T, WS, and RH on ambient PM concentrations during the considered period were taken into account, and it was found that the PM concentrations correlate, with different magnitudes and strengths, positively with T and negatively with RH and WS.

Nowadays, UAVs are widely used in various sectors including military, agricultural, social and other fields. There are two types of UAV control, the first uses remote control or remote control and the second the aircraft is flown independently or on autopilot. The results of the MBKM research at the Yogyakarta College of Aerospace Technology campus in 2022 resulted in several shortcomings, including having a heavier mass than a UAV wing made from balsa wood with a weight difference of 874 grams and another problem, namely that the wing's straight geometric shape will cause more resistance. so big that it needs to be changed to a morphing wing. Based on the shape of the wing and the problems, the researchers tried to correct these deficiencies by forming a new geometry. The design of this research uses CFD and FEA methods to determine deformation and pressure values. With research results. Pressure distribution on the wing surface using CFD simulation displays contour velocity and contour pressure. For contour pressure, use a velocity of 21 m/s, 22 m/s, 23 m/s, 24 m/s, 25 m/s which flows through the front of the airfoil. At a speed of 21 m/s the maximum value is 26.89 m/s, then if the speed increases then the maximum value will also increase. At a speed of 25 m/s the maximum value is 32.03 m/s. At a speed of 21 m/s the maximum value of deformation is 0.33164 mm, at a speed of 22 m/s the maximum value of deformation is 0.3515 mm, at a speed of 23 m/s the maximum value of deformation is 0.37107 mm, at a speed of 24 m/s the maximum value of deformation is 0.55469 mm, and at a speed of 25 m/s the maximum value of deformation is 0.56883 mm.

Species Compotition of Fruit Bats (Pteropodidae) in Institut Teknologi Sumatera, Lampung

Fruit bats (family Pteropodidae) pollinate around 300 species of tropical plants of high economic value over a wide range of areas. This large role does not match the status of their population, which continues to decline due to habitat loss, particularly in urban areas. The Sumatra Institute of Technology (ITERA) campus, which is currently under development, may result in habitat changes that may affect bats. These concerns have led to the need for research into bat diversity on the ITERA campus. The result could be utilised to monitor and develop the environmental management of the campus. The research was conducted from May to September 2023 in five different habitat types. Data were collected using 3 mistnets and 3 night repetition each habitat. The data were analysed using indices of diversity, evenness and species richness. The study recorded 143 individuals of 7 species. The highest number of species and diversity was observed in the sengon and rubber habitat (6 species). The lowest number of species and diversity was found in the botanical garden (2 species).

Exploring online teaching and learning challenges for the technical and vocational education and training lecturer

This paper explored the challenges lecturers face in teaching through online platforms. Online learning has become increasingly prevalent in Technical and Vocational Education and Training (TVET) institutions, offering opportunities and challenges for TVET lecturers. The transition from traditional face-to-face teaching to online environments requires lecturers to adapt to the new teaching methods, design engaging content, and navigate digital platforms. The qualitative research gathered data from 35 lecturers out of 60 conveniently and purposefully selected from five engineering campuses at a South African TVET college. Participants were accessible to the researcher and possessed online teaching experiences. Participant observation was used as a data-gathering tool. The study attempts to answer the question: What challenges are lecturers facing during online teaching and learning? The Technological Pedagogical Content Knowledge Framework for Teacher Knowledge by Koehler and Mishra guided the study. Data were analysed thematically from the identified patterns and themes. The findings revealed technical difficulties like connectivity and software glitches, which disrupted the teaching and learning process. Lecturers grappled with receiving practical online support. The limited interaction and collaboration among students in virtual settings posed additional challenges in maintaining engagement and addressing individual learning needs. Furthermore, access and equity issues hindered students' ability to participate fully due to inadequate technology, internet access, and power outages. To overcome these challenges, the study recommended lecturers continuous professional development in online learning methods and technologies. Addressing the challenges contributes to the successful implementation of online learning in the TVET sector by ensuring quality education and enhancing students' skills and competencies.

Assessment of Carbon Neutrality and Sustainability of KCAET Campus in Kerala, India

The study was conducted during 2021–22 with a view to analyze the carbon neutrality and sustainability of Kelappaji College of Agricultural Engineering and Technology (KCAET) campus. It was done for proposing and implementing sector-wise adaptation and mitigation strategies to develop KCAET campus of Malappuram district in Kerala as a “Carbon Neutral Campus”. A carbon emission and sequestration analysis in the sectors of food consumption, transportation, energy, waste and AFOLU (Agriculture, Forest and Other Land Use) was done. The required data were obtained by conducting various surveys, and the corresponding emission factors were taken from available literatures. Carbon emission and sequestration of each sector was calculated as the product of the emission factor and activity data. The total carbon emission from the campus was found to be 522.086 CO2 eq.t and the total sequestration from the campus was 177.2 CO2 eq.t. Since the carbon emission is higher than carbon sequestration, it can be inferred that the campus is not carbon neutral. Strategies for achieving and maintaining carbon neutrality through reduction in emissions, improving stock of carbon and creating carbon credits/reserves need to be adopted. Since the major emission is from transportation and use of fuels, energy efficient methods to save energy and switching to renewable energy sources to bring down the emissions from energy consumption need to be implemented.

The impact of the visual layout of university open space on students' behavior and satisfaction level: the case of Iran University of Science and Technology

PurposeVisual aesthetics are a vital aspect of environmental quality. The objective of this study is to demonstrate the implementation of visibility analysis and visual quality standards on a campus to enhance productivity and effectiveness.Design/methodology/approachThis study has identified the most crucial and valuable metrics for evaluating the visual quality of open spaces through an analysis of theoretical foundations and relevant background information. To achieve research goal, a multi-method approach was employed, incorporating a survey, user satisfaction ratings and ISOVIST simulation techniques. Specifically, this study focused on assessing the quality of open spaces in three open areas located on the campus of the Iran University of Science and Technology.FindingsBased on the study’s findings, the most significant factors that students considered when evaluating the visual quality of open spaces on the Iran University of Science and Technology campus were green areas, gathering spaces and architectural elements such as furniture, color and texture. Among the three open areas examined, “Open Space One” was identified as the most satisfactory location for students. According to the study, “sensory richness,” “complexity” and “mystery” were significant indicators of students' satisfaction in this area. This area also had the widest radius and field of view feasible, which gave it a feeling of openness and spaciousness.Originality/valueThis study explores the influence of students' experiences, behavioral patterns and visual analyses on their use of open spaces on university campuses, with a focus on the Iran University of Science and Technology. By assessing students' satisfaction levels with these spaces, this research provides valuable insights that can guide the initial analysis stage before the design process and facilitate design optimization during the development stages. The results highlight the importance of considering user experiences and visual analysis when planning and creating open spaces on university campuses.HighlightsConducting an initial analysis before developing a design plan can be very helpful in understanding how users think and behave.The three criteria of visual quality that have the strongest correlation with students' satisfaction with “open space” are “mystery,” “sensory richness” and “complexity.”Two factors, namely the “radius of vision” and the “area” index, significantly influence students' satisfaction with open spaces.Outdoor designers should incorporate “green space” and “gathering spaces” into their designs since the presence of these is effective in attracting and satisfying students.The number of people using an open space has little to do with how satisfied students are with it.Half of the students use open areas between 11:00 and 14:00, so the provision of “canopy” and “shelter” in these spaces is essential.

Implementasi REST API Media Informasi Kehilangan dan Penemuan Barang Berbasis Android (Studi Kasus: Kampus 1 Universitas Teknologi Yogyakarta)

Losing an item is a condition where a person part with an item that previously existed to become non-existent. Yogyakarta Technology University students still often experience lost items around campus area 1. Students who experience loss usually use social media to spread information to each other, but this is still less effective because the information uploaded by students can be covered by the content or status uploaded. by other students. The impact that occurs when there is no information system is that the dissemination of information related to lost and found items is not on target so that it is more difficult for students to find their lost items again. The aim of this research is to design a system as a medium for information regarding the loss and discovery of goods in the Yogyakarta University of Technology campus 1 area. The method in this research uses the waterfall model. The results of this research are to produce an Android-based application that can make it easier for students to exchange information regarding lost and found items around the Yogyakarta University of Technology campus 1 area so that it is easier for students to find and return items to students who have lost items.

Impact of urban canopy characteristics on turbulence dynamics: Insights from large eddy simulation

In this study, a series of large-eddy simulations are conducted to explore the dynamics of turbulence within the urban canopy. Two idealized urban-like geometries (staggered and aligned arrays of cubes) and one real urban region (located on the Southern University of Science and Technology campus in China) are simulated under neutral atmospheric conditions. The results show a significant difference in the dispersive momentum fluxes between OpenFOAM and PALM within the ultra-dense arrays. Furthermore, it is found that the spatial layout does not exert a significant effect on the budget of turbulent kinetic energy. Instead, it mainly depends on the ratio of the building surface area to the total surface area, i.e., packing density. In addition, a multi-scale coupled inflow boundary condition is introduced in this study to simulate the flow in a real urban area. This boundary condition yields a better match to the LiDAR measurements than the Weather Research and Forecasting model data. Finally, this study shows that the mean velocity obtained from the campus of SUSTech is in satisfactory agreement with the data from low-density idealized cube arrays and the corresponding urban canopy model. This observation suggests that mean wind speeds within partially occupied urban areas are relatively independent of wind direction, thus greatly improving the application of urban canopy models to such scenarios.

A pilot project for energy retrofit of educational buildings - The engineering campus of the University of L’Aquila

The engineering campus of the University of L’Aquila represents a complex use case in the context of energy efficiency, mainly due to its size, the high thermal power, the hybrid hydronic and ventilation system, the absence of a room’s thermal control, and the progressive obsolescence of the heating plant. An in-depth recognition and study of the campus’ HVAC system made it possible to assess the main energy inefficiencies and define interventions to improve its performance. The energy retrofit, carried out by the University’s “Energy Commission Workgroup”, highlighted the main criticalities and potentials of the HVAC system providing viable paths for energy optimization. Among them, one of the hypothesized interventions concerned the thermal regulation of the heating plant, which is, to date, substantially absent. This work presents the results of a Pilot Project to quantitatively evaluate the effectiveness of the closed-loop control on a thermal system. Two classrooms in the Engineering Campus, similar in geometry, orientation, and occupancy, were selected. One of them has been equipped with a control system. The results of the monitoring campaign showed that the proposed system achieved more than 30% energy savings over a three-month trial period.

Identification and antibiotic sensitivity profile of potential bacterial toxin producers from some foods sold to students within Enugu state university of science and technology (ESUT) campus

Food borne diseases have become major public health burden and bacteria especially the toxin producers have been mostly implicated as among the most common causative agents. Thus, the need to screen and identify most frequent bacteria associated with ready to eat foods consumed within ESUT campus. The food samples were chicken, egg, tomato, vegetable salad and dried fish. A total of 25 samples were collected, with 5 for each sample .They were cultured for bacterial isolation using selective media prior to phenotypic characterization via morphology and biochemical analysis . The predominant isolates were further subjected to genotypic characterization using 16S rRNA sequencing. Each identified isolate of inoculum size of 1.5x 108cfu/ml was exposed in-vitro to analytical Gram+ve and Gram-ve antibiotics by disc diffusion method .The results revealed the presence of Staphylococcus aureus strain OPD001-1 in 5samples, Citrobacter werkmanii strain UMH18 in 3 samples, Salmonella enterica subsp. entericaserovar strain CFSAN027396 in 4 samples, Salmonella enterica subsp. entericaserovar typhimurium in 4 samples and Salmonella enteric strain 2011k-1440 in 4 samples and Salmonella enteric subsp. entericaserovar in 5 samples respectively. Their antibiotic susceptibility pattern differed. Gram positive Staphylococcus aureus was susceptible (>20mm) to 7 test antibiotics (Erythromycin, Levofloxacin, Cephalexin, Ciprofloxacin, Gentamicin, Ofloxacin and Clindamycin ) and resistant (<14mm) to 3 (Cetriaxone, Ampicillin and Cloxacillin). Citrobacter werkmanii and Salmonella enteric subsp. entericaserovar demonstrated similar susceptibility (>20mm) to 7 test Gram-ve antibiotics but resistant to Amoxicillin, Streptomycin and Gentamicin while Salmonella enterica strain 2011k-1440 and Salmonella enteric subsp. entericaserovar typhimurium were resistant (<14mm) to Nitrofurantion , Cetriaxone and Amoxicillin. Although these bacterial isolates can be inhibited by some antibiotics, their implications as potential toxin producers including the heat stable ones pose health problems to food consumers.
