The YAM-BIO ontology alignment system is an extension of YAM++ but dedicated to aligning biomedical ontologies. YAM++ has successfully participated in several editions of the Ontology Alignment Evaluation Initiative (OAEI) between 2011 and 2013, but this is the first participation of YAM-BIO. The biomedical extension includes a new component that uses existing mappings between multiple biomedic...

the study assessed the post-harvest management information needs of yam farmers in kogi state. interview schedules were used to collect data from 189 yam farmers who were randomly selected from the four agricultural zones of the state (zone a, b, c and d) by using multistage random sampling techniques. the data collected were subjected to descriptive statistics and binary logit regression. resu...

Yam is a major staple in West and Central Africa and an important supplementary food in East Africa. Three varieties of yam are grown in Sub-Saharan Africa (SSA), though only two are indigenous to the region. White yam (D. rotundata) and yellow yam (D. cayenensis) are native to West Africa, and the production area stretches from central Cote d‘Ivoire to Cameroon. East African production of wate...

The present study seeks to evaluate the influence of the time of harvest on the phenolic composition, antioxidant activities and anti-cholinesterase action of processed yellow yam (Dioscorea cayenensis). HPLC-DAD analysis of the processed yellow yam revealed the presence of some phenolic acids and flavonoids. The result showed a higher amount of most of the identified phenolic compounds in the ...

Stakeholders operating within the yam export market lack shopper insights to formulate effective marketing and supply chain management strategies. This paper aims to show how supermarket loyalty card data on yam shoppers in the UK can be analysed to objectively assess marketing performance and prospects through year-on-year comparison of key marketing measures and regression. The results demons...

The physical and functional properties of trifoliate yam flours processed using different pre-treated methods at varying harvesting periods were examined. The flours were subjected to physical (bulk density) and functional (water absorption, solubility and swelling power) analyses. The bulk density values for the trifoliate flours ranged from 0.54-1.03 g/cm3. The parboiled flours had higher bul...

The first fatal case of Yam bean and Rotenone toxicity in Thailand was studied at Forensic Medicine, Chiang Mai, Thailand. A Chinese Taiwan man, 59 years old, was found dead after Yam bean ingestion. Yam bean toxicity and death have been found very rarely in the world and has not been reported in Thailand The Yam bean plant is grown widely in Northern Thailand. But many people know that mature ...

this study examined farmers’ perception and adoption of yam minisett technology. the study was carried out in anambra state, nigeria. a sample size of 120 yam farmers was used for the study. data were collected using a structured and validated interview schedule. data generated for the study were summarized using descriptive statistics such as frequency, percentage and mean scores while the sig...

This study investigated the impact of processing on retention of iron and zinc in D. rotundata. Fresh tubers were processed into boiled yam and yam flour and analyzed for zinc, iron, and physicochemical properties. Percent true retention (%TR) was assessed using paired samples and a formula that compensated for loss or gain of moisture and soluble solids. The retention of iron ranged from 55.5%...
