ABSTRACT.
The 14th African Society of Human Genetics (AfSHG) Morocco Meeting and 2nd International Congress of the Moroccan Society of Genomics and Human Genetics (SM2GH), held in Rabat, Morocco, from December 12 through 17, 2022, brought together 298 attendees from 23 countries, organized by the AfSHG in collaboration with the SM2GH. The conference’s overarching theme was “Applications of Genomics Medicine in Africa,” covering a wide range of topics, including population genetics, genetics of infectious diseases, hereditary disorders, cancer genetics, and translational genetics. The conference aimed to address the lag in the field of genetics in Africa and highlight the potential for genetic research and personalized medicine on the continent. The goal was to improve the health of African populations and global communities while nurturing the careers of young African scientists in the field. Distinguished scientists from around the world shared their recent findings in genetics, immunogenetics, genomics, genome editing, immunotherapy, and ethics genomics. Precongress activities included a 2-day bioinformatics workshop, “NGS Analysis for Monogenic Disease in African Populations,” and a Young Investigators Forum, providing opportunities for young African researchers to showcase their work. The vast genetic diversity of the African continent poses a significant challenge in investigating and characterizing public health issues at the genetic and functional levels. Training, research, and the development of expertise in genetics, immunology, genomics, and bioinformatics are vital for addressing these challenges and advancing genetics in Africa. The AfSHG is committed to leading efforts to enhance genetic research, coordinate training, and foster research collaborations on the continent.

Published: May 2024

Several Uvariodendron species are known for their scented leaves and stem bark, hence this study. The leaves, twigs, stem and root barks of the newly described Uvariodendron species, U. mbagoi Dagallier and Couvreur from Kwedijela forest (KF) and Kimboza Forest Reserve (KFR) collected in dry and wet seasons, were steam distilled to yield essential oils that was more abundant in the root bark (2.07-3.85%) than in the leaves, twigs and stem bark (0.09-0.71%). The essential oils from the root bark collected from KF in the wet season (2.07%) was slightly lower than that obtained from the plant part collected from the same locality during the dry season (3.85%). GC-MS analysis indicated that linalool was the most prominent constituent of the leaf (82.18%, KF) and (98.86%, KFR), twig (89.66%, KFR), and stem bark (97.97%, KFR) oil while methyl eugenol (41.08%, KFR) and elemicin (39.28%, KFR) were the major constituents of the root bark oil. The essential oil from the leaves, stem bark, twigs and root bark of U. mbagoi exhibited mild to moderate potency when screened for antioxidant, antibacterial, and protease (trypsin) inhibitory activities.

Published: May 2024

From diverse or indole-3-carbaldehyde, certain unique indol-3-yl-4H-pyran derivatives were generated by condensing with different nucleophiles. IR, 1HNMR, and elemental studies have all confirmed their chemical structures. The green catalyst for the formation of indol-3-yl-4H-pyran derivatives is a zinc-linked amino acid complex [Zn(L-proline)2]. Furthermore, the environmental friendliness of this synthetic technique was investigated by assessing the reusability of the Zn(L-proline)2 complex over five consecutive cycles with no significant loss of catalytic activity. This novel process has showed substantial advantages in terms of safety, simplicity, stability, mild conditions, a short reaction time, excellent yields, and good purity without the use of organic solvents. The antibacterial properties of the compounds produced were investigated and discovered to be promising. To determine whether compounds are appropriate as possible insecticidal agents, the toxicological activity of the synthesized compounds against Cowpea aphid, Aphis craccivora, was tested using leaf dip bioassay technique toxicity studies performed in the laboratory.

Corrosion, wear and machinability studies on scrap aluminium alloy wheel based metal matrix composite
Authors: P. Ravi V. , A. Sankaran R. 
Published: May 2024

Recycled materials, especially scrap aluminum alloy wheels with reinforcement castings, are gaining applications in various fields such as aerospace, naval, military, and automobile. In this research, Honda car alloy wheels are stir-cast with 5% alumina as reinforcement and subjected to corrosion, wear, and machinability studies. Corrosion studies were conducted to evaluate the corrosion current density (ICorr), corrosion potential (ECorr), and corrosion rate for the cast aluminum metal matrix composite. The wear studies with different loads, i.e., 50 N, 60 N, 70 N, and 80 N, were performed on the specimen and investigated the coefficient of friction, frictional force, and pin temperature. The sliding load has a significant effect on wear performance, and for the sliding load of 80 N, the wear recorded was 2574.83 µm. The electrochemical machinability studies with voltage, duty cycle, and concentration of citric acid electrolyte are performed on the machining rate and surface corrosion factor. Analysis of the electrochemical machining process with PROMETHEE-II shows that 7 V, 60% duty cycle, and 30 g/L electrolyte concentration are estimated to be the best combination for a higher machining rate and a lower surface corrosion factor.

Published: May 2024

In this work, we report the effect of cetyl trimethyl ammonium bromide (CTAB), ethyl di-tetra amine (EDTA) and polyacrylamide as surfactants on synthesis of zinc oxide for photocatalytic application. The ZnO nanoparticles were synthesized with and without the surfactants and characterized using powder X-ray diffraction (PXRD), and Fourier transform infrared spectroscopy (FTIR). In addition to this, the morphology of zinc oxide prepared in the absence and presence of these surfactants investigated through scanning electron microscopy (SEM). As confirmed from XRD and FTIR characterization results, the use of different surfactants did not affect the composition of ZnO nanomaterials. The photocatalytic activities were investigated by the degradation of methylene blue (MB) dye under sunlight irradiation. To optimize the effects of operational parameters, the study was carried out as a function of dye concentration, catalyst dose, and pH on the degradation efficiency of the photocatalysts. The optimum values of catalyst dose, dye concentration and pH of solution were found to be 0.09 g, 5 mg/L and 10, respectively. The ZnO nanomaterials prepared with CTAB surfactant showed highest degradation efficiency of 98% indicating potential application for practical decontamination of wastewater from toxic organic pollutants.

The Biafra Story in Film: An Appraisal of Biyi Bandele’s <i>Half of a Yellow Sun</i>
Authors: Onwuliri Edmund Chukwuma 
Published: May 2024

Diverse scholarly and artistic expressions in book form and documentary films have been employed to document the story of the Nigerian Civil War by persons who were actively or peripherally involved in the events surrounding it. Attempts at telling the story have been coloured by different factors like military, political, ethno religious and egocentric considerations. This study examined the war's account through Biyi Bandele’s Half of a Yellow Sun, a filmic adaptation of Chimamanda Adichie’s novel with the same title. Using qualitative content analysis method and grounded on the Trauma and Cinema Theory, the study examined the film’s representation of historical facts and how such perspectives may have been received. The film's reception by the Nigerian cinema audience and government through the cinema regulatory authority were examined. The study concluded that the suppression of critical historical facts in the film through censorship represents the unwillingness of the government to allow for citizen conversation, which the film could provoke and which may lead to proper closure and possibly lay to rest, the ghost of the fratricidal war that almost ripped the country apart between July 1967 and January 1970.
An Assessment of Kwasi Wiredu’s Contributions to African Philosophy of Religion
Authors: Talabi Joseph Moyinoluwa , Okusanya Samuel Oludare 
Published: May 2024

The African philosophy of religion has come of age. However, laying the groundwork and shaping its intellectual trajectories was the work of eminent thinkers and philosophers who laboured in recent years. Kwasi Wiredu is one of the scholars who stood tall and strong with the depth of his thoughts and perspectives seemingly traversing the scope of time and space. In light of the overarching objective of this study “to decisively relaunch African philosophy of religion as a self-sustaining field of African philosophy,” it behoves that a review of Wiredu’s contribution to the field is critically examined, considering the postmodern categories and contexts. Using an analytical approach, this paper shows that Kwasi Wiredu’s contribution to the discourse on the substance and nature of Africa is highly informative and enlightening, though it is open to dispute and reflections just like every other philosophical work. A brief review of the catalogues of Wiredu’s scholarly works shows that the issues of conceptual decolonization, cultural reconstructionism and the nature of African philosophies underscore his work. The article argues that for contemporary philosophers, it behoves that Wiredu’s analytic framework may be adopted. But, culturally-inclined and realistic approaches should be adopted in doing Africa philosophy. The diversities of African cultures and traditions as well necessitate a pluralistic approach from various parts of Africa.
A Contrastive Analysis of Word Formation Processes in Interrogating Widespread Democratic Decay and Breakdown in some West African Countries
Authors: Odusote Abiodun 
Published: May 2024

In contemporary times democracy is threatened across West African states like never before. Democracy is under increasing assault from the elected leaders and their cronies. A noticeable, subtle, stifling strangulation of democratic structures and substance leads to the erosion of democracy in more than a few West African countries and a total breakdown of democracy through coups in others. Despite the attempts by the ECOWAS and AU to discourage democratic breakdown in Africa, military intervention continues to truncate democracies in many African countries. This paper interrogated the root-causes of the prevalence of democratic breakdown in West African countries and the factors sustaining military interventions in the region. Building upon earlier scholarly work on democratic breakdown and deploying the doctrinal research methodology, the researcher analysed the resurgence of and effects of military intervention and truncation of democratic practices in West Africa. The findings of this research showed that military intervention is edging West African countries to the precipice and there have been more than a few complete democratic breakdowns in West African countries in recent times. In conclusion, the researcher offers suggestions on how democratic breakdown can be arrested in the West African region and/or reduce its occurrence by advocacy, enthronement of good governance, citizenship participation, application of the rule of law, and upholding of constitutional provisions.

В статье анализируются проблемы противодействия молодежному экстремизму в условиях информационной войны. Преступники распространяют фейки, занимаются агитационно-пропагандистской деятельностью с целью внесения в общество смуты, разжигания межнациональной розни. Наибольшему влиянию подобной информации подвержена молодежь. Молодежный экстремизм – это те идеологии, которые больше всего захватывают молодежь, они могут основываться на культе агрессии, силы, призывать к насилию и убийствам тех, кто не разделяет их взгляды или является идеологическим противником. Молодежь, охваченная экстремистскими идеями, имеет целью навязать традиционному обществу свои взгляды, применяя для этого силу.The article analyzes the problems of countering youth extremism in the context of information warfare. Criminals spread fakes, engage in agitation and propaganda activities in order to bring unrest into society, incite ethnic hatred. Young people are most affected by such information. Youth extremism are the ideologies that most capture young people, they can be based on the cult of aggression, force, call for violence and murder of those who do not share their views or are an ideological opponent. Young people caught up in extremist ideas aim to impose their views on traditional society by using force to do so.

Authors: Conners Ryan , Cochrum Robert , Northcutt Cristina , Radden Haley , Powell Dakota , Wiethop MaryAnn 
Published: May 2024

Introduction: Firefighting is a physically demanding occupation, which involves tasks such as rescuing victims, pulling a hose, and carrying a ladder. Thus, firefighters must have excellent cardiovascular fitness (CF). However, the cumbersome movement and added mass of firefighting personal protective equipment (PPE) can place additional stress on the cardiovascular system, not accounted for through traditional CF testing.Purpose: Determine the effect of wearing PPE on predicted CF compared to athletic attire (AT) in firefighter (FF) cadets completing the Forestry Step Test (FST). Methods: Male and female (N = 17) FFs performed two trials of the FST, one trial completed in PPE and one in AT. Recovery heart rate was measured at the end of each trial and predicted VO2max was calculated. Paired samples t-tests compared heart rate and predicted VO2max values between the PPE and AT conditions.Results: Predicted VO2max (p < 0.001) was lower in the PPE (37.53 + 3.20 ml.kg.min-1) compared to the AT condition (46.35 + 7.63 ml.kg.min-1).Conclusion: Predicted aerobic capacity is lower when wearing PPE compared to AT using the FST as the aerobic capacity assessment method. The effect of PPE on CF effort of firefighting should be considered when developing assessments.
