More about Aggrey and Akori beads
No full textThis contribution is a further continuation of a discussion, begun by Professor Mauny and continued by the present author, into the nature and provenance of the aggrey or akori beads formerly imported into the Gold Coast (i.e. the south of modern Ghana). It considers at length the evidence provided by E.J.P. Brown, a notable Fante personality of the early twentieth century, in his book, The Gold Coast and Asianti Reader (1929), and compares this with some actual bead samples and with linguistic and literary evidence not used in the earlier discussion. This evidence leads to the tentative conclusions that : 1) The original and most prized blue aggrey/akori bead was made of glass ; 2) It was identical with the Yoruba segi bead ; 3) Its import into the Gold Coast may have ceased in the mid nineteenth century ; 4) That its principal place of manufacture may have been Ife, where glass working may also have ceased in the mid nineteenth century.Cette contribution reprend un débat entamé par R. Mauny et poursuivi par l’auteur sur la nature et la provenance des perles aggrey ou akori importées autrefois en Gold Coast (sud du Ghana actuel). On analyse méthodiquement les arguments fournis par E J. P. Brown, un notable Fanti du debut du XXe siècle, dans son livre, The Gold Coast and Asianti Reader (1929) et on les confronte avec des échantillons actuels de perles et avec des preuves linguistiques et littéraires non utilisées dans les discussions antérieures. Cette argumentation permet de proposer les premières conclusions suivantes : 1) L’ancienne perle bleue aggrey/akori, qui était la plus appréciée, était faite en verre ; 2) elle était identique à la perle yoruba segi ; 3) son importation en Gold Coast semble avoir cessé à partir du milieu du XIXe siècle ; 4) son principal lieu de fabrication peut avoir été Ifé où la manufacture du verre peut aussi avoir cessé au milieu du XIXe siècle.Fage John Donnelly.

A genetic variation map for chicken with 2.8 million single-nucleotide polymorphisms
No full textWe describe a genetic variation map for the chicken genome containing 2.8 million single-nucleotide polymorphisms (SNPs). This map is based on a comparison of the sequences of three domestic chicken breeds (a broiler, a layer and a Chinese silkie) with that of their wild ancestor, red jungle fowl. Subsequent experiments indicate that at least 90% of the variant sites are true SNPs, and at least 70% are common SNPs that segregate in many domestic breeds. Mean nucleotide diversity is about five SNPs per kilobase for almost every possible comparison between red jungle fowl and domestic lines, between two different domestic lines, and within domestic lines--in contrast to the notion that domestic animals are highly inbred relative to their wild ancestors. In fact, most of the SNPs originated before domestication, and there is little evidence of selective sweeps for adaptive alleles on length scales greater than 100 kilobases

DETERMINANTS OF DIET AND FLUID ADHERENCE AMONG END STAGE RENAL DISEASE PATIENTS UNDERGOING HAEMODIALYSIS AT MOI TEACHING AND REFERRAL HOSPITAL, UASIN GISHU COUNTY, KENYA
No full textPurpose: This study was conducted to establish determinants of diet and fluid adherence among ERSD patients undergoing hemodialysis at Moi Teaching and Referral Hospital- Uasingishu county. Kenya.
Methods: A descriptive cross-sectional study design was applied. Using Fisher\u27s formula, a sample size of 145 participants were conveniently recruited. Data collection was done by use of modified end stage renal disease adherence questionnaire (ESRD-AQ). Chi-square (χ2) was used to test statistical significance. Frequency tables and bar graphs were used for data presentation. SPSS version 22.0 was used for data analysis.
Results: The study revealed that knowledge on nutritional requirements for renal patients was marginally associated with dietary and fluid intake with a higher proportion of those with low nutritional knowledge (83.6%) adhering to diet and a relatively smaller proportion in the same category (58.9%) complying with fluid intake. A significant relationship with dietary adherence was observed where participants practiced fluid restrictions (p=0.003) and the frequency in which health staff talk about the importance of following proper diet (p <0.0001). On social support domain, a significant association was observed in patients who agreed that various social support aspects help improve depression, self-esteem, self-management, etc. and who adhered to diet scored a significantly higher mean of 5.6 (95% CI = 5.5 - 5.6) in contrast to non-adherent counterparts who had a mean of 5.5 (p = 0.0006). Among the economic factors with significant association with diet adherence were; use of bus for transport (p=0.02); income of less than KSH. 30,000 (p=0.006); treatment cost (p=0.007) and ability to access material support that helps in adherence (p=0.003). Those who claimed that lack of transport was the main reason for missing dialysis practiced fluid adherence (p=0.01) with a smaller proportion (44%) adhering to fluid restriction in comparison to 70.8% who had transport and were non- adherent.
Unique contribution to theory, practice and policy: The study findings are unique to the study site and it\u27s hoped that it can be used to inform hospital policy makers in addressing adherence challenges in ESRD patients on hemodialysis. The study recommends a holistic study on determinants of adherence to hemodialysis, medication use, dietary, and fluid compliance among patients undergoing HD at MTRH should be conducted in order to produce generalized results

Structural Analysis of a Pedal-Powered Maize Sheller
No full textCapstone Project submitted to the Department of Engineering, Ashesi University in
partial fulfillment of the requirements for the award of a Bachelor of Science degree in
Mechanical Engineering, May 2021In Ghana, maize is one of the highest-yielding cash crops, but the supply chain is severely
hampered by the lack of access to machines for processing. This study conducts a structural
analysis on a low-cost, pedal-powered maize sheller, designed and fabricated by the author
and found to operate with a high shelling rate and low kernel damage. To inform an
improved iteration of the design, structural analysis was carried out along the lines of
reliability of the bearing that was used, factor of safety for both static and fatigue loads,
weight optimization, and trend forecast for shelling performances. Using a reliability of
90%, a 180409 Instrument Precision ball bearing was calculated to have a life cycle of
3468.44 hrs which fell in the range needed for agricultural equipment. Moreover, the static
and fatigue analysis revealed yield strength values that were higher than the applied stresses.
As such, they were deemed safe, except for the bicycle cleats, which needed fillets to reduce
stress concentrations. From the weight optimization, it was determined by the author that
one-fourth of the cylinder stand's weight can be removed to save on material without
hampering the assembly's structural integrity. Lastly, using a forecast of shelling trends, a
trade-off was discovered between kernel damage and shelling rate.Ashesi Universit
MiR-Explore: Predicting microRNA precursors by class grouping and secondary structure positional alignment
No full textMicroRNAs (miRNAs) are small noncoding RNAs that regulate gene expressions by targeting the mRNAs especially in the 3′UTR regions. The identification of miRNAs has been done by biological experiment and computational prediction. The computational prediction approach has been done using two major methods: comparative and noncomparative. The comparative method is dependent on the conservation of the miRNA sequences and secondary structure. The noncomparative method, on the other hand, does not rely on conservation. We hypothesized that each miRNA class has its own unique set of features; therefore, grouping miRNA by classes before using them as training data will improve sensitivity and specificity. The average sensitivity was 88.62% for miR-Explore, which relies on within miRNA class alignment, and 70.82% for miR-abela, which relies on global alignment. Compared with global alignment, grouping miRNA by classes yields a better sensitivity with very high specificity for pre-miRNA prediction even when a simple positional based secondary and primary structure alignment are used. © the author(s), publisher and licensee Libertas Academica Ltd

To download, navigate to Log In in the top right-hand corner of this screen, then select Log in with my UTSA ID.The full text of this item is not available at this time because the author has placed this item under an embargo until August 1, 2025.The online pharmacy industry is growing globally, including in the developing world. This study explores the role of online pharmacies in Ghana from the pharmacists’ perspective. In particular, it seeks to understand how pharmacists perceive online pharmacies in Ghana in terms of their larger socio-cultural, policy, and communication dimensions, as well as challenges that they face and foresee in implementing online pharmacies given the resource-poor settings in Ghana. Twenty-one in-depth interviews were conducted and analyzed using the thematic analysis approach. Findings indicate that while online pharmacies were in a nascent stage in Ghana, most pharmacists perceived them as beneficial, offering benefits such as convenience, enhancing access to medication, reducing violence, and gender discrimination against women in the pharmacy profession. Also, online pharmacies were perceived to bridge the gap in care between the hospitals and the community pharmacies and in addressing some of the cultural barriers that have long impeded clients from accessing care. On the other hand, respondents pointed to the lack of adequate infrastructure such as roads, internet connectivity, addressing systems acting as hindrance to Ghana's online pharmacy. Finally, it was noted that involving and communicating with varied stakeholders was key to the success of the online program. This study will help online pharmacy industry players in Ghana understand the industry's general scope, its benefits, pitfalls, challenges, and the way forward.Communicatio
