Rocket Fin Test Fixture Development & Exploration of Rotation Inducing Fin Design

The purpose of this senior project was to develop a method of applying rotation inducing rocket fin concepts to rockets for the benefit of the University of Akron Akronauts; the student led rocket design team. The project was performed independently of the team’s current efforts as a research and development endeavor for future team projects. Main project goals were divided into three parts: design a fin test fixture for verification testing in the University’s wind tunnel, develop a parameter-driven software model that could be used to generate design options with theoretical performance data as an output, and run fluid dynamics analyses to offer additional support to findings. At a higher level, this project was chosen as an opportunity to exercise a few of the many different facets of the engineering process. Over the course of the project, our team received valuable experience with: idea generation and brainstorming, concept vetting, technical software programming, process troubleshooting, rapid prototyping, and aerodynamic-related testing

Information resources availability, utilisation and job performance of academic librarians in selected university libraries in North-Central Nigeria

This study examined the level of information resources availability, utilisation and job performance in selected university libraries in North-Central Nigeria. Four research questions and three hypotheses were tested at 0.05 level of significance. Task-Technology Fit was the theoretical framework underpinning the study. The study population consisted of 128 academic librarians in seven university libraries. Out of this total, 103 copies were duly completed and returned for quantitative analysis, giving a response rate of 81%. Sampling was purposive and enumerative as all members of the population were used for the study. Data collected were analysed using SPSS. Findings indicated that 90% of the respondents noted that there is high availability of information resources for their job performance while 77(75%) of the respondents revealed that there is high utilisation of e-resources. A relationship between the level of information resources utilisation and academic librarians\u27 job performance was established in the selected university libraries at (β= 0.591; p\u3c0.05). The hypotheses tested revealed that job performance was significantly related to information utilisation. Though information availability was found to be positively related to job performance, the relationship was not statistically significant (β= 0.081; p\u3e0.05). Theoretically, the study contributed to validating Task-Technology Fit Theory. Based on these findings, some recommendations were made. Keywords: Availability, Job Performance and Utilisation

Nexus between information resources accessibility and academic librarians job performance: A case study of North-Central, Nigeria

This article examined the relationship between information resources accessibility and academic librarians\u27 job performance in North-Central, Nigeria. Maslow and Task-Technology Fit theories underpinned this study. A descriptive survey research design was adopted for the study. The quantitative methods research approach of the explanatory type was adopted as means of data collection from 135 academic librarians, out of which 103 (81%) copies of the questionnaires were duly filled and returned. The data collected were analysed using frequency counts and percentages. Two research questions and one hypothesis tested at 0.05 level of significance were postulated for the study. The major findings revealed that the five most accessible print information resources are textbooks, newspapers, journals, encyclopaedias and dictionaries while the least accessible include indexes, manuscripts and technical reports. With regards to accessibility of information resources, findings showed that there is a need for libraries to subscribe to more e-resources and provide greater access links. Findings further indicated that a relationship between the level of information resources accessibility and academic librarians\u27 job performance was established in the selected university libraries at (β= 0.591;

Awareness, accessibility and challenges of social media as experienced by postgraduate information studies students, University of KwaZulu-Natal during the COVID-19 pandemics lockdown

Students who receive literacy training tied to real-life assignments show greater improvement in literacy scores. The significance of this study revolves around the prominent role accorded social media in academic community for research, teaching and learning. In spite of the benefits associated with the use of social media for academic purposes, it is observed that many students, teachers/lecturers have not been fully exploring these advantages to improve their academic performance. The study investigated the awareness, access and social media challenges encountered by postgraduate students of Information Studies, UKZN during the lockdown caused by COVID-19 pandemics. The study employed a quantitative research design in form of an online questionnaire, using Google Forms. Fifty-five post-graduate students were sampled, of which 51 participated, giving a response rate of 93%. The findings revealed (Facebook, Instagram, Zoom, Twitter and WhatsApp) as major (100%) types of social media available for post graduate students for their academic purpose. The findings further revealed smartphone as a major tool for accessing social media by the respondents (96%), and the major challenges restraining students from effectively utilising social media for academic activities. The study underscores the importance of social media in an academic environment and offers some recommendations that could lead to more informed and effective use of social media for academic purposes

Evaluation of three medicinal plant extracts against Plasmodium falciparum and selected microganisms

Background: A great revival of scientific interests in drug discovery has been witnessed in recent years from medicinal plants for health  maintenance. The aim of this work was to investigate three Nigerian  medicinal plants collected in Nigeria for their in vitro antiplasmodial and antimicrobial activities.Materials and Methods: Extracts obtained from parts of Persea americana, Jatropha podagrica and Picralima nitida and their fractions wereevaluated for in vitro antiprotozoal and antimicrobial activity.Result: The methanol extract of P. nitida demonstrated activity against chloroquine-sensitive and chloroquine-resistant P. falciparum clones with IC50 values of 6.3 and 6.0 µg/mL, respectively. Methanol and chloroform extracts of P. americana seed showed antifungal activity against Cryptococcus neoformans IC50 less than 8 and 8.211 µg/mL respectively. Finally, the petroleum ether extract of P. americana had activity against methicillinresistant Staphylococcus aureus (MRSA) with an IC50 value of 8.7 µg/mL.Conclusion: The study revealed the antibacterial and antiplasmodial activities of the plants extracts at the tested concentrations.Keywords: Antifungal, Antibacterial, Persea americana, Picralima nitida, Jatropha podagrica, Plasmodium falciparu

DESIGN AND ANALYSIS OF LEAF SPRING IN A HEAVY TRUCK

A leaf spring is a simple form of spring, commonly used for the suspension in wheeledvehicles. Leaf Springs are long and narrow plates attached to the frame of a trailer that rest above or below the trailer's axle. There are monoleaf springs, or single-leaf springs, that consist of simply one plate of spring steel. These are usually thick in the middle and taper out toward the end, and they don't typically offer too much strength and suspension for towed vehicles. Drivers looking to tow heavier loads typically use multileaf springs, which consist of several leaf springs of varying length stacked on top of each other. The shorter the leaf spring, the closer to the bottom it will be, giving it the same semielliptical shape a single leaf spring gets from being thicker in the middle. Springs will fail from fatigue caused by the repeated flexing of the spring. The aim of the project is to design and model a leaf spring according to the loads applied. Presently used material for leaf spring are forged steel. In this project we are going to design leaf spring for the materials Mild Steel and composite material Glass Carbon by varying reinforcement angle. We are going to check the strength variations while changing reinforcement angle. For validating this design we are conducting FEA  Structural Analysis is done on the leaf spring by using two different materials Mild Steel and Glass Carbon. Modal and fatiuge Analysis is also done. Pro/Engineer software is used for modeling and ANSYS is used for analysis

Designing a Locally Manufacturable Wheelchair for Nepal

People with disabilities in developing countries often lack the basic equipment needed to assist them in their daily lives. International Nepal Fellowship (INF) is a Christian medical organization located in Nepal that provides medical care and assistance to people with disabilities and other conditions. Currently, INF imports expensive wheelchairs that undergo a prolonged border process before being received. INF has reached out to the Collaboratory to design a wheelchair that can withstand the challenges of Nepal’s terrain and can be manufactured from local materials. The Nepal Wheelchair team has set out to design a wheelchair that can fulfill their needs. In previous work, the team researched wheelchair designs and took a trip to Nepal. From this trip, more information was gained, an initial prototype was constructed, and locally available materials and parts from Nepal were brought back. This year, as a result of knowledge gained through constructing the second prototype, many design changes were tested and implemented. The team researched standards and created testing procedures to ensure the changes to the rear wheel mount, caster wheel mount, footrest, and seat design would uphold the strength and durability of the wheelchair. These design changes have enhanced patient safety and experience in the wheelchair while still keeping the design easily manufacturable. The team also researched options for adding push rims and through using a roller bender were able to construct them. Moving forward, the team will continue to finalize manufacturing documentation and take a second trip to Nepal this May.
