Skills acquisition for publishers in the sir: demands, plans and prospects
(Extension Publications Limited, 2025) Adegbore, A. M.
Fifth Industrial Revolution (5IR) ushers in a human-centred technological paradigm with artificial intelligence (Al) and emerging technologies combined with human imagination, ethics and individualisation. This study examines the significance of 5IR to the publishing industry in terms of the skill needs, preparedness, strategic action and possibilities emerging for publishers. Thematic analysis of fifteen peer-reviewed articles was conducted using a systematic literature review guided by the PRISMA framework to address five critical research questions. The findings reveal that the most critical skills for publishers in 5IR are digital literacy, data analytics- flexibility, emotional intelligence and knowledge of Al uses. Whilst others are entering digital-human collaborative environments via modular systems an: shared infrastructures, the majority are ill-prepared due to infrastructural attitudinal and strategic deficits. New models of professional development like individualised learning routes and networked experiences, are also identified as the key to equipping publishers with 5IR-relevant skills. All the same, barriers like resistance to change, decreasing access to training an: legacy CPD routines persist. Despite such challenges, conversion e: publishing practices based on 5IR principles is of significant benefit including efficiency of operations, tailored provision of content, global access and sustainability of the industry in the long term. The article concludes by recommending interventions at the policy level, training, infrastructure an: innovation to facilitate publishers to convert to the demands of the 5IR age These findings are critical not just to the professional growth of publishers but also to the applicability of the publishing industry within a more digitalised and human-centric knowledge economy.
Colonial transformation of women's economic roles in Okpella, Edo State, 1904–1960
(2025) Abolorunde, A. S.; Arebamen, D. D.
Nigerian colonial history vis-à-vis women's studies has attracted scholarly attention. These studies range from women’s roles in the textile industry in Abeokuta, women’s riots in Egba land and the Aba women's riot. Historians and anthropologists have also interrogated women and taxation in Ijebu Province, as well as their leading roles in the decolonisation process. However, none of these studies has adequately addressed how colonialism transformed the economic role of women in Okpella from 1904, when Iddo-Okpella was designated as the administrative district of Etsako land by the British, to 1960, the year of Nigeria’s independence. This neglect reduces our comprehensive understanding of the workings of the colonial economy, despite the monumental contributions of Okpella women. This study examines the colonial transformation of women's economic roles in Okpella, Edo State, Nigeria. Drawing on archival records from the National Archives, Ibadan, colonial correspondence, and oral interviews with women, which reveal women's participation and displacement in the mining industry, it traces the shift from pre-colonial subsistence agriculture, food crop production, and periodic market trading to broader proto-industrial activities under British rule. Key policies—monetisation, cash crop promotion, taxation, market stall rentals, and extractive industries—initially expanded opportunities in crafts, retail trade, and mining labour, particularly gold prospecting (1940s) and limestone extraction post-1955. However, patriarchal assumptions, mechanisation, and discriminatory labour practices marginalised women in mining by 1960, prompting a return to agriculture and crafts. The paper, in its conclusion, highlights how colonial exploitation, despite rhetorical development aims, ultimately positioned Okpella women to contribute significantly to the colonial economy in Nigeria, thereby intensifying the incorporation of the Nigerian economy into the global market.
The prospect of using modified local starches from cocoyam and wheat starches as fluid loss material in a water - based drilling
(Nigerian Institute Of Industrial Engineers, 2017) Akintola, S. A.; Ogundipe, M.
As an oil producing nation, Nigeria embarks on substantial drilling activities. The additives used for these activities are all imported as a result there is need to reduce the over dependency on foreign additives this has necessitated the sourcing locally for suitable substitute. During drilling, adequate filtration control is essential to prevent drilling problems such as excessive torque and drag; differential pressure sticking; borehole instability; and formation damage. This study was aimed at a comparative analysis of the use of wheat starch and cocoyam chemically modified with ammonium phosphate and sodium acetate as suitable fluid loss additives in a water-based mud. The filtration properties of a water- base fluid formulated with variable quantities of the chemically modified starch were determined using the recommended standard API practice at different conditions of temperatures with Carboxymethylated Cellulose CMC used as control. Using Eviews 7, the statistical analysis showed drilling fluid formulated with starches treated with sodium acetate had a fluid loss value in the range of 4.0 - 8.9 mls, while those from starches modified with ammonium phosphate had a fluid loss of 4.3 - 8.3 mls; although, these values were lower than 9.1 - 11.1 mls for CMC formulated mud, the results show that mud sample treated with modified wheat starch and cocoyam starch can significantly reduce fluid loss in a water based drilling mud, thereby confirmed that polymer can be used as fluid loss control agent in the mud system.

Conversion coating pretreatment enhances pipeline integrity
(Open Science, 2018) Makanjuola, O.; Adediran, A. A.; Ogunsemi, B.; Akintola, S. A.; Ebitei, C.
It is necessary to coat both the internal and external surfaces of pipelines which transport different types of fluids that are usually contaminated with various percentages of aggressive corrosives. Pipelines pass through various terrains and highly challenging environments hence the need for both internal and external coatings to prevent corrosion and its adverse effects. In order to improve on the longevity of pipelines and the adhesion of the coating system, it is preferable to conversion coat blasted surfaces prior to application of any coating system. Improvements in pipeline coatings applications and the often neglected chromating procedure prior to coating application have been highlighted. This will prolong the lifespan of pipeline networks and secure these strategic assets from being a source of both materials and human resources drain pipes. However, the use of corrosion resistant alloys as internal lining for carbon steel pipes in the petroleum/gas industry is fast gaining recognition.
