  • Book Chapters  
    Review books or articles provide a critical and constructive analysis of existing published literature in a field, through summary, analysis, and comparison, often identifying specific gaps or problems and providing recommendations for future research. These are considered as secondary literature since they generally do not present new data from the author's experimental work. Review articles can be of three types, broadly speaking: literature reviews, systematic reviews, and meta-analyses. It also the researcher to stay abreast of new literature in the field.
  • Conference Proceedings and Papers  
  • Grey Literature  
    Grey literature consists of research and information produced outside conventional publishing channels, such as reports, policy briefs, working papers, and conference materials. It offers valuable insights and data that complement peer-reviewed sources, supporting research, policy, and practice.
  • Heritage Materials  
  • Institute of African Studies (IAS) J. H. Kwabena Nketia Archives  
    The J. H. Kwabena Nketia Archives preserve Ghanaian and African cultural heritage through music, oral traditions, photographs, and audiovisual collections. Guided by Professor Nketia’s vision that African traditional arts must be collected, preserved, practiced, and continually inspire creative expression, the Archives serve as a living resource for scholarship, teaching, and innovation

    Performance Evaluation of Radiotherapy Treatment Planning System Using the Cirs Thorax Phantom.
    (University of Ghana, 2024) Akrobotu, C. K.
    Treatment Planning System (TPS) authentication is essential for ensuring accurate dose calculations in radiotherapy. This study verified the Varian Eclipse TPS algorithm using a CIRS Thorax phantom, for a 6MV photon beam in conformal radiotherapy. A CT stimulator was used to scan the phantom, and TPS was used to plan eight distinct irradiation geometries simulating conformal radiotherapy. Dose measurements were taken using ionization chambers, and The differences between the measured and computed dosages were examined. The findings demonstrate the variation between measured doses and calculated doses by the TPS were 1.57% and 3.88% respectively within the acceptance criteria of ±5%. The TPS consistently delivered accurate dose calculations even under complex conditions such as oblique incidences and blocked fields. The CT to electron density conversion assessment all measured values within the acceptance criteria of ±20HU.The study validates the Varian Eclipse TPS algorithms’s precision in dose delivery ensuring patient safety. The CIRS Thorax phantom proved competent for the routine TPS verification.

    Development And Evaluation Of Gluten-Free Rice Bread Formulated With Hydrocolloid-Protein Additive Systems
    (Food and Humanity, 2025-12-09) Mensah, P.O.; Tutu, C.O.; Akonor, P.A.; Bempah, J.O.; Asiedu, B.K.; Adusei, H.O.; Saalia, F.K.
    The structural and sensory limitations of gluten-free bread remain a major challenge in baking, particularly in formulations based on rice flour. This study explored the effects of xanthan gum, egg powder and gelatin powder, both individually and in combination, on the rheological behaviour, structural quality and sensory acceptability of gluten-free rice bread. Five formulations (F1-F5) were developed, with F1 serving as the control. Key quality parameters, thus, including dough firmness, adhesiveness, cohesiveness, loaf volume, specific volume, bread density, moisture content, crumb texture, crust appearance and sensory attributes, were evaluated. The formulation containing all three additives (F5) exhibited the best performance across nearly all metrics. F5 recorded the highest loaf volume (1295.7 ± 21.8 cm³), the lowest bread density (0.48 ± 0.02 g/cm³), the highest moisture content (36.8 ± 0.5 %) and the most preferred crust appearance (L* value = 42.3 ± 1.1; score = 8.0 ± 0.4). Rheological properties also showed significant enhancement, with F5 displaying the highest dough firmness (275.3 ± 4.2 g) and cohesiveness (93.1 ± 2.6). Principal Component Analysis (PCA) revealed strong positive correlations between F5 and key quality indicators such as crumb texture, overall acceptability and consistency. Mechanistic interpretation suggested that xanthan gum improved dough viscosity and water retention, egg powder contributed protein coagulation during baking and gelatin enhanced elasticity and moisture stabilisation. These synergistic effects resulted in gluten-free bread with structural, sensory and visual characteristics that closely approximate wheat-based bread. The results provide a strong formulation strategy for producing high-quality gluten-free bread with improved consumer appeal and functionality
