Effect of fiber orientation-based composite lamina on mitigation of stress intensity factor for a repaired plate: a finite element study
Authors: Shaikh Abdul Aabid , Baig Muneer , Hrairi Meftah , Mohamed Ali Jaffar Syed
Published: May 2024

The bonded composite repair has proven to be an effective method for addressing crack damage propagation. Numerous studies have employed experimental and simulation techniques to demonstrate the repair performance through the composites. These studies have explored various parameters related to bonded composites, such as size and properties, to enhance repair effectiveness. However, one aspect that has not been thoroughly investigated is the impact of fiber orientation within the composites. Therefore, the current work investigates the effect of the fiber direction of the composite patch bonded on a thin plate under plane stress conditions. Three types of fiber orientation of composite patch have been considered. In this investigation, the finite element method was used to determine the stress intensity factor using the ANSYS commercial code. The research findings showed that the fiber direction influenced the mitigation of stress intensity factor. This study is particularly important for designing the composite patch based on the fiber direction.
Dose Reduction in Medical Radiography: Advancing Veterinary Diagnostic Solutions
Authors: Kocaova Huseyin Yavuz , Tunçel Nina , Unal Nuri
Published: May 2024

In this study, we investigated photon attenuation using an anti-scatter lead grid with a flat panel detector (FPD) and aimed to mitigate it by implementing a linear array detector (LAD). We developed a mechanical system that facilitates X-ray scans using the LAD. For comparison, we selected a standard FPD unit. To assess the differences in entrance skin dose (ESD) between the LAD and FPD systems, we initially utilized anthropomorphic phantoms, followed by water phantoms for exposure tests. Results showed that at a water depth of 10 cm, the ESD from the LAD was 22% lower than that from the FPD. At 30 cm this ratio was increased up to 40%. As water thickness increased, the benefits of using LAD became more evident, demonstrated by a lower ESD. This finding highlights the potential utility of implementing this equipment in veterinary radiography, particularly for imaging animals and their anatomical sites with thicker tissues.
Dichotomy and Difference: A Social History of Army Wives in Nigerian Cantonments, 1905-1985
Authors: Nzemeka Justus Adim
Published: May 2024

This article examines the nature of the dichotomy and difference between officers’ and non-commissioned officers’ wives in Nigerian Cantonments. It identifies that the interactions between the two groups since the colonial period have long been overlooked in intellectual discourse and knowledge production due to culture and sex stereotypes. The paper argues that the relationship between officers and non-commissioned officers’ wives in both colonial and post-colonial periods were marked by rank and social inequality. In this piece, we draw on primary and secondary sources of data, oral interviews, official documents, internet materials, and participant-observation to substantiate its claim, this paper reveals that the case of army officers’ wives and non-commissioned officers’ wives in Nigeria epitomizes the theory of social stratification in a male-dominated profession. Contrary to the opinion that it is only men that marginalise women, this paper demonstrates that women also marginalise fellow women on account of rank and social construct. It also affirms that colonial encounters reinvented inequality and dichotomy in gender relations and military life. The study concludes that rank is important but social inclusion will foster cooperation and collaboration in a plural society.
From Non-Interference to Adaptive Pragmatism: China’s Security Policy in Africa
Authors: Gazibo Mamoudou , Lema Abdou Rahim
Published: May 2024

China’s growing focus on African peace and security has generated discussions on its longstanding foreign policy principle of non-interference in the internal affairs of African countries and most of that growing body of research have argued that China is doing away with its foreign policy principle. Drawing its conclusions from a careful analysis of China’s security engagement with African countries, this paper argues that, forced to deal with various African crises, China has been pragmatically adaptive. This adaptive pragmatism has allowed Beijing to get involved in Africa’s peace and security landscape without overtly compromising its traditional posture on non-interference.

Authors: Netshivhambe Evans
Published: May 2024

Venda musicians incorporate aspects of “traditional” Venda life and music while still trying to make their music marketable to a larger audience. Johannesburg, the “City of Gold” was never such for many popular Venda musicians as their music did not yield any gold for them. Two significant influences take center stage in realizing a wider market for popular Venda music. These influences reference melodic and rhythmic motifs from indigenous Venda music and children’s songs, while retaining a touch of “homegrown” in the music. Interviews with several popular musicians and an analysis of music indicates cultural relevancy in popular Venda music quoting.
African Vernacular-rooted Imagery in Yemi Ikisakin’s Stone Sculptures
Authors: James Sule Ameh
Published: May 2024

This article presents a critical analysis of the African vernacular-rooted imagery represented in Yemi Ijisakin’s stone sculptures produced between the years 2006 and 2016. The focus on this period is to study the kinds of imagery he represents when there is a global artistic shift to installation and conceptual art. In doing this, I argue that even though Ijisakin’s stone sculptures are deemed vernacular art, they are not indigenous or historical African art, but a rethinking that references indigenous African cultural registers. The article also focuses on the ideas and meanings the interpretations of the works communicate to the audience. Thus, this article presents his artworks to a mainstream journal given that they have not received any critical analysis on the grounds that his works are regressive and outside the normative standards for referencing African/Nigerian/Yoruba contexts. But his works are important for demonstrating the interdependence of art and culture in Nigeria and producing knowledge on cultural practices.
From the Cradle to the Grave: A Feminist Stylistic Reading of Select Poems from Juka Jabang’s The Phoenix
Authors: Bassin Boye Abdou , Fayyaz Shafaq
Published: May 2024

This study examines the use of poetic artistry as a contribution to social reformation in Juka Jabang’s The Phoenix to highlight the cultural and social tendencies that contribute to the oppression of women in the Gambian context. It draws attention to the oppression of Gambian women not just as a general societal predisposition, but as a phenomenon deeply rooted in the most fundamental unit of the family. Using Sarah Mills’ model of feminist stylistics, the article aims to explore the use of point of view, agency, metaphor, and transitivity to expose the socio-cultural beliefs and practices that perpetuate the oppression of women in Gambian society. The study adopts a qualitative, linguistic-cum-literary analysis based on four poems purposively selected from the collection on the basis of their thematic preoccupation with the plight of women in a male-dominated society. The analysis also pays attention to the literary devices appropriated by the poet in a bid to poeticize the experience of Gambian women at the hands of an unrelenting male hegemony. The analysis reveals that cultural beliefs in the so-called superiority of the male child, the ostensible impurity of uncircumcised women, the submissiveness of women particularly in marriage, and the professed right to multiple wives as major factors that legitimize the oppression of women in Gambian society.
Technology Transfer from China to Kenya for Transport Infrastructure: The Case of International Trunk Roads
Authors: Mulaku Lemmy Nyongesa
Published: May 2024

Literature on technology transfer to Africa is dominated by studies on agribusiness, military technology, information and communication technology, energy, climate change, health, and manufacturing, while it is scanty on others like transport infrastructure. In this article, we reviewed literature and carried out key informant interviews to collect data on technology transfer for Chinese-built roads in Kenya. Our objective was to examine the extent of technology transfer from Chinese multinational corporations to Kenyan institutions and organizations. We established that there was little technology transfer mostly because of Kenya’s internal obstacles such as inadequate absorptive capacity, weak competition culture, and weak legal and institutional frameworks on technology transfer. Multinational corporations transferred technology primarily to fulfil their commercial objectives and to meet the domestic labour training requirements. The technology transferred was not sufficient to simulate innovation and technology development in Kenya. We recommend reviewing Kenya’s legal and institutional frameworks on international technology transfer in order to improve the participation in and enforcement of technology transfer by government institutions.
In His Own Words: Reflections on a Scholarly Career with Rene Lemarchand
Authors: Leinweber Ashley
Published: May 2024

What is the role of scholars in envisioning the continent and bearing witness to historic events?  This paper is based on an interview with Professor Rene Lemarchand, renowned scholar of the former Belgian colonies of the African Great Lakes. His earliest book Political Awakening in the Belgian Congo is based on fieldwork conducted in 1960 as the country was undergoing decolonization and describes the political crises of early independence. In the 1970s, he explored the concept of clientelism and role of ethnicity in Central Africa. As events unfolded in Burundi and Rwanda, Lemarchand became an expert on genocide. His career an Africanist has been devoted to understanding political violence in Central Africa while envisioning a better future for its people. The piece will explore reflections not only on his long career, but also its contribution to our understanding of the history of ethnic violence and genocide in the Great Lakes and beyond.
