An appraisal of Nigeria's foreign policy role in Africa's development, 2010-2022
Authors: Nzewigbo, Adaora Appolonia  
Published: January 2024

Nigeria's foreign policy is a strategic instrument intricately woven into the fabric of its national interests. Since its independence in 1960, Nigeria has steered an external strategy with the African continent at its nucleus, emblematic of its steadfast commitment to nurturing stability and prosperity across Africa. Through varying administrations, the Nigerian government has consistently upheld the core tenets of its foreign policy, steadfastly adhering to its Afrocentric orientation. This study examined Nigeria's foreign policy's role in the developmental trajectory of Africa during the period from 2010 to 2022. Employing a qualitative methodology, it harnesses secondary data from a comprehensive review of esteemed academic sources, including textbooks, scholarly journals, authoritative reports, and online repositories. Systems theory was applied to guide the research. The findings clearly illustrate Nigeria's pronounced contributions through its Afrocentric foreign policy paradigm – engendering unity, catalysing collaboration, nurturing peace and stability, and directing developmental resources to regions characterized by harmonious relations. Ultimately, this study illuminates the comprehensive spectrum of Nigeria's impact on Africa's developmental odyssey, ranging from active regional leadership participation to counter-terrorism endeavours and poverty abatement. Consequently, this research advocates for a sustained optimization of Nigeria's contributions, thereby fortifying internal tranquillity and urging a meticulous evaluation of the underlying socio-political tensions within Nigeria.Nzewigbo A.

Social factors contributing to harmful child vending practices among children in Zimbabwe: The case of Epworth
Authors: Magavude Tafadzwanashe James  
Published: January 2024

The study explored the social forces behind harmful child vending practices in Zimbabwe. The research was triggered by an observation that vending has become one of the most menacing challenges among children in Zimbabwe. The objective of the study was to explore social factors contributing to child vending in Zimbabwe. This research was informed by the Ubuntu-oriented Social Work, Welfare and Development Theory. A number of previous studies that focused on the same subject and age-group were consulted. The research utilized qualitative research methodology, in which four key informants were purposively selected for interviews and the convenience sampling (used to get the 12 child vendors who participated through in-depth interviews) and also the 6 community members (whom the researcher interacted with through focus group discussions). The research findings revealed that poverty is a leading factor forcing children in Zimbabwe to engage in vending. The research also revealed that some of the factors contributing to child vending include, child abandonment, orphanhood, bad modeling, and misinformation. The study recommended collaborative efforts to be made between government and other stakeholders in coming up with interventions to support children subjected to vending and other harsh conditions.How to cite this article using ASWNet styleMagavude T.

O objetivo deste estudo foi comparar o desempenho, equilíbrio dinâmico e o padrão de movimento de praticantes de treinamento de força (TF) e fitness funcional (FF). Participaram do estudo 22 homens (TF: 31,00 ± 3,77 anos; 84,30 ± 12,79 kg; 1,76 ± 0,09 m; IMC: 26,99 ± 2,55; FF: 30,00 ± 5,93 anos; 84,24 ± 10,44 kg; 1,75 ± 0,05 m; IMC: 26,66 ± 2,27), com pelo menos um ano de experiência. Cada participante visitou o laboratório em três ocasiões com intervalo variando entre 24h e 48h entre as visitas. Na primeira visita foi realizada coleta dos valores antropométricos e teste de uma repetição máxima (1RM) e, na segunda, o reteste de 1RM. Na terceira visita foram realizados os testes Illinois Agility Test (IAT), Agility T Test), Y Balance Test (YBT) e Functional Movement Screen (FMSTM). Foi observada uma menor mediana no Agility T Test (p=0,002), assim como uma maior pontuação total no FMSTM (p=0,038) no grupo FF. Nenhuma diferença significativa foi observada para o IAT (p=0,154) e para a força muscular relativa (supino reto: p=0,226; agachamento: p=0,489). Os resultados permitem concluir que, mesmo com diferenças biomecânicas e fisiológicas entre ambas as modalidades de exercícios, os resultados obtidos são semelhantes. A significância no Agility T Test e no FMSTM revelam uma leve tendência superior na capacidade de mudança de direção e padrão de movimento para o grupo FF, fato este que não é corroborado pelo IAT.

ABSTRACT
Objective: To compare Lacosamide and Levodopa for treating restless-legs-syndrome in hemodialysis patients in terms of mean change of International Restless Leg Syndrome (IRLS) score.
Methods: It was a Randomize control trail done at Department of Medicine & Nephrology Department of Mayo hospital, Lahore from April 2019 to March 2020. After taking approval from institutional-Review-board (IRB) of the King Edward Medical University (KEMU), sixty patients coming to hemodialysis unit of Mayo Hospital, Lahore and fulfilling the inclusion criteria were enrolled for study. We used lottery method and randomly divided them in to two groups that is Group-A: Lacosamide (50 mg) given at bedtime. (30 cases) and Group-B: Levodopa (110 mg) given daily 2 hours before bedtime (30 cases). Treatment was continued for 4 weeks. We calculated IRLS score at start of study and four week after treatment and any Change from baseline was calculated for every patient. That difference of –IRLS score documented on the attached Performa along with demographic details about patient.
Results: This study showed that after 4 weeks of treatment there was not much difference seen in International Restless Leg Syndrome score in each treatment groups. i.e. [Pre-Treatment (Lacosamide: 20.80±4.78 vs. Levodopa: 22.60±4.66), Post Treatment (Lacosamide: 14.20±2.89 vs. Levodopa: 15.73±3.58), Mean change of score (Lacosamide: 7.10±4.99 vs. Levodopa: 6.86±6.63 . p - Value = 0.878)
Conclusion: This trial concludes that Levodpoa and Lacosamide were equally good in treating Restless-Legs-Syndrome among patients who are on Hemodialysis.

Magnesium isotope fractionation processes during seafloor serpentinization and implications for serpentinite subduction
Authors: Nielsen Sune G. , Klein Frieder , Marschall Horst R. , Pogge von Strandmann Phillip A. E. , Auro Maureen 
Published: January 2024

Abstract. Studies of magnesium (Mg) isotope ratios in subduction zone lavas have revealed small, but significant offsets from the mantle value with enrichments in the heavy isotopes. However, the very high concentration of Mg in the mantle contrasts with much lower concentrations in the subducted igneous crust and oceanic sediments, making these subduction components unlikely vehicles of the Mg isotope anomalies in arc lavas. Only serpentinites, which in various proportions form part of oceanic plates, have high Mg contents comparable to fresh mantle rocks and have thus been considered a potential source of exotic Mg in the source of arc magmas. In this study we analyzed serpentinite samples from different oceanic settings for their Mg isotopic compositions. The majority of samples are indistinguishable from the depleted mantle (δ26Mg = −0.24 ± 0.04 ‰) irrespective of their origin. Only a small number of seafloor-weathered serpentinites are slightly enriched in the heavy isotopes (up to δ26Mg = −0.14 ± 0.03 ‰), implying that bulk serpentinites are unlikely sources of isotopically anomalous Mg in subduction zones. We also developed a partial-dissolution method in which 5 % acetic acid for 180 minutes was shown to fully dissolve the minerals brucite and iowaite while leaving the serpentine mineral chrysotile essentially undissolved. Partial dissolution of 11 bulk serpentinite samples revealed a Mg isotopic composition of brucite (±iowaite) that is systematically ~0.25 ‰ heavier than that of coexisting serpentine. Thus, preferential breakdown of brucite and/or iowaite in a subducted slab prior to serpentine could preferentially release isotopically heavy Mg, which could subsequently be transported into the source region of arc magmas. Such a scenario would require brucite/iowaite breakdown to occur at pressures in excess of 3 GPa and produce fluids with very high concentrations of Mg that could be transported to arc magma source regions. Whether these conditions are met in nature has yet to be experimentally investigated.
An LES Model for Wind Farm-Induced Atmospheric Gravity Wave Effects Inside Conventionally Neutral Boundary Layers

Published: January 2024

Abstract. The interaction of large wind farm clusters with the thermally-stratified atmosphere has emerged as an important physical process that impacts the productivity of wind farms. Under stable conditions, this interaction triggers the creation of atmospheric gravity waves (AGWs) due to the vertical displacement of the boundary layer by the wind farm. AGWs induce horizontal pressure gradients within the boundary layer that alter the wind speed distribution within the farm, influencing both wind farm power generation and wake development. Additional factors, such as the growth of an internal boundary layer originating from the wind farm entrance and increased turbulence due to the wind turbines, further contribute to wake evolution. Recent studies have highlighted the considerable computational cost associated with simulating gravity wave effects within large eddy simulations (LES), as a significant portion of the free atmosphere must be resolved due to the large vertical spatial scales involved. Additionally, specialized boundary conditions are required to prevent wave reflections from contaminating the solution. In this study, we introduce a novel methodology to model the effects of AGWs without extending the LES computational domain into the free atmosphere. The proposed approach addresses the wave reflection problem inherently, eliminating the need for these specialized boundary conditions. We utilize the recently developed multi-scale coupled (MSC) model of Stipa et al. (2023b) to estimate the vertical boundary layer displacement triggered by the wind farm, and apply the deformation to the domain of an LES that extends only to the inversion layer. We validate our AGW modeling technique for two distinct free atmosphere stability conditions, comparing it to the traditional approach in which AGWs are fully resolved using a domain extending several kilometers into the free atmosphere. The proposed approach accurately captures AGW effects on the row-averaged thrust and power distribution of wind farms while demanding less than 15 % of the computational resources compared to traditional methods. This can be further reduced in cases of conventionally neutral boundary layers, since there is no longer a need for solving the potential temperature equation. The developed approach is used to compare global blockage and pressure disturbances obtained from the simulated cases against a solution characterized by zero boundary layer displacement, which represents a limiting case of very strong free atmosphere stratification. Finally, we discuss the implications of making such "rigid-lid" approximation, instead of considering the full gravity wave solution, when predicting wind farm power.
