DEVELOPMENT OF AN IMPROVED PEDAL POWERED WASHING MACHINE

This research work deals with the design and fabrication of an improved cloth washing machine capable of small-scale industrial applications as well as household use. The project is aimed at developing a washing machine that is efficient, affordable, durable and compatible for rural areas with little or no supply of electricity; by working on the efficiencies of pre-developed machines and providing solutions to their deficiencies; a dynapod with gear-sprocket system combined with the belt-pulley system is used to transmit torque via leg cranking to the shaft of the washing drum (agitator in an electric washing machine); the dynapod is also used to vary (increase or decrease) the speed of the machine to facilitate different speeds for the three main operations in laundry process washing, rinsing, and spinning which are the three main operations of the washing machine, speed is further increased with the aid of the belt-pulley system. With an overall efficiency of 84.98%, the cost of fabricating the machine is 45,000NGN (123.80USD) and this can be significantly reduced if produced in a large scale. The machine is easy to use and maintain as the system of operation is simple, it is eco-friendly and safe for the user. The machine is capable of community application therefore can be used by the entire populace of a rural area or settlement

DEVELOPMENT AND PERFORMANCE EVALUATION OF A RECONFIGURABLE PLATFORM FOR A MICROSATELLITE PRODUCTION

The process of satellite assemblage, integration and testing is challenging and requires considerable care. Hence, the provision of a support platform which provides easier mechanical mounting and unmounting within a design facility and its sources of mechanical disturbance. The provision of an indigenous low-cost platform to cater for microsatellite production is sought, and in this research, a partially reconfigurable platform to produce microsatellites (mass range between 10-100 kg) was developed. The materials used for the fabrication were carefully selected, and considerable attention was placed on the overall weight of the platform based on various criteria such as Density, Yield strength, Modulus of elasticity. The Computer-Aided-Design (CAD) for the various parts using Solid works was done, which also involved the design in accommodating the two standardized diameters for launch vehicle adapters for microsatellites. The design calculations necessary for the completion of this work and weight budget analysis was done to determine the final weight of the platform. Analysis System (ANSYS) software was used to validate the structural integrity of the platform under loading conditions. The stress analysis of the platform in a vertical position which is the most critical loading case was performed. Also, there was no mechanical damage or failure found on the platform. The procedure adopted for the development of the equipment can be used on the development of similar projects. The developed machine is both manually and mechanically operated. The developed platform has the capacity of carrying a maximum satellite weight of 150 kg

This advert makes me cry: Disclosure of emotional response to advertisement on Facebook

As social media is transforming how consumers interact with brands and how brand-related content is consumed, this paper aims to investigate if and how Facebook users express their emotions towards advertisements of brand share on the site. Seven hundred and three comments about the Lloyds 250th Anniversary advertisement on Facebook were analysed as positive, negative or neutral attitude towards the advert. Facebook users found the advertisement emotionally appealing and voluntarily report their emotion of love, pride and in some cases anger. The presence of an iconic image like the black horse and the cover music was found to be emotionally appealing. The background music as well aroused positive emotions and engaging. This study introduces the possibility of analysing Facebook comments on brand content to understand consumers’ emotional responses and attitudes to the brand. Managers can explore these opportunities to identify what consumers find interesting in advertisements and how best to develop their creative strategies. It also offers the opportunity to allocate resources better to engage consumers with creative advertisement. Unlike interviews or surveys, this is a pioneering study on measuring emotional responses to advertisement through users’ self-report on social media

Making a Christian Private University Appealing to Prospective Students: The Case of Covenant University

Worldwide, universities are established to train highly skilled manpower that are expected to contribute to the development of their societies. Nigerian universities are expected to contribute to the achievement of the national goals using education as a tool. Before 1993, the provision of university education in Nigeria was a government monopoly. Many people could not be offered admissions into public universities because the existing facilities could not accommodate the deluge of requests. However, private universities have entered into the higher education service provision market. With many of them competing for prospective student enrolment, it is not surprising that some of them have deployed marketing strategies to attract students and make them stand out from the cluttered market. This paper examines how Covenant University, a Christian faith-based university and the acclaimed leader in the private university industry in the country has marketed itself. It found that it uses its product, people, work processes and serene physical location to attract new students. Importantly, it uses its relatively high tuition fees to position itself as the school for the children of the elites

“So what if ChatGPT wrote it?” Multidisciplinary perspectives on opportunities, challenges and implications of generative conversational AI for research, practice and policy

Transformative artificially intelligent tools, such as ChatGPT, designed to generate sophisticated text indistinguishable from that produced by a human, are applicable across a wide range of contexts. The technology presents opportunities as well as, often ethical and legal, challenges, and has the potential for both positive and negative impacts for organisations, society, and individuals. Offering multi-disciplinary insight into some of these, this article brings together 43 contributions from experts in fields such as computer science, marketing, information systems, education, policy, hospitality and tourism, management, publishing, and nursing. The contributors acknowledge ChatGPT's capabilities to enhance productivity and suggest that it is likely to offer significant gains in the banking, hospitality and tourism, and information technology industries, and enhance business activities, such as management and marketing. Nevertheless, they also consider its limitations, disruptions to practices, threats to privacy and security, and consequences of biases, misuse, and misinformation. However, opinion is split on whether ChatGPT's use should be restricted or legislated. Drawing on these contributions, the article identifies questions requiring further research across three thematic areas: knowledge, transparency, and ethics; digital transformation of organisations and societies; and teaching, learning, and scholarly research. The avenues for further research include: identifying skills, resources, and capabilities needed to handle generative AI; examining biases of generative AI attributable to training datasets and processes; exploring business and societal contexts best suited for generative AI implementation; determining optimal combinations of human and generative AI for various tasks; identifying ways to assess accuracy of text produced by generative AI; and uncovering the ethical and legal issues in using generative AI across different contexts

To build my career or build my brand? Exploring the prospects, challenges and opportunities for sportswomen as human brand

Research question: There are growing concerns about the commercial viability of sportswomen as they are seldom featured as brand ambassadors. There are challenges for sportswomen in building and making their brands appealing to advertisers and marketers. This study seeks to understand the human brand concept in the context of sportswomen. Specifically, exploring the challenges, prospects and opportunities, sportswomen face in building their brand. Research methods: Qualitative data from semi-structured interviews with 24 sportswomen in the UK were thematically analysed. Results and Findings: Sportswomen seldom recognise themselves as brands and therefore make little effort to build their brand. They identified known issues such as limited media coverage, gendered perceptions of women’s sport, as well as emergent issues such as the challenges of balancing the need to develop their brand with the need to build their career. We develop a human brand pyramid to highlight how sportswomen can progress from human brands to brand endorsers and boost their earning potential. The present findings contribute to a better understanding of human brands, sportswomen and celebrity endorsement. Implications: It offers practical implications for sportswomen who want to build their brand. Governing bodies, media and brands also need to change the representation of sportswomen across advertisements through tactics that promote gender equity and decrease differences. Sportswomen’s athletic abilities should be given more visibility over their aesthetics. Talent managers also need to be mindful of trends in gender relations to better support their female clients in developing their brands

Inherent Microorganisms Affects the Quality of a Nigerian Fermented Beverage “Agadagidi” During Production

This research produced wine from unripe plantain fruits using spontaneous fermentation method. The period of production was five days. The purpose of this study was to isolate and identify microorganisms associated with unripe plantain fruits, determine the physicochemical parameters of the fermenting medium. Microbial count, foaming density, alcohol content, enzymes assay, sensory analysis, physicochemical properties, mineral content, antioxidants properties, and antinutrient content of the sample were investigated every 24 h for 5 days. A total of seven bacteria and four fungi consisting of yeasts and moulds were isolated during the study. The microbial loads of bacteria and fungi of the unfermented plantain fruits were 8.0 × 106 ± 0.01 cfu/mL and 14.2 × 104 ± 0.01 sfu/mL respectively. The temperature (ºC), pH and titratable acidity (%) ranged from 25.55-32.50, 4.51-5.50 and 0.99-3.50 respectively. The sample was observed to be colourless all through the fermentation periods. Turbidity of the samples increased during fermentation from 43.50 to 111.00. The data obtained from this work has shown the importance of unripe plantain micro-flora in the production of “Agadagidi”. It is also concluded that consortium of microorganisms inherent within the plantain fruits are involved in plantain fruits fermentation. This information can contribute to a better understanding of the “Agadagidi” production process for a consistent quality beverage
