For the purpose of constructing yam cDNA libraries, attempts to isolate high quality RNA using several previously reported protocols were unsuccessful. Therefore a protocol was standardized for yam total RNA isolation by using guanidium buffer at the Department of Biology, Virginia Sate University. The RNA isolated using this standardized protocol was high in quality and led to successful good ...

The aim of this research was to analyze the allocative and technical efficiency yam production using data envelopment analysis (DEA). A purposive simple random sampling technique used 100 producers were selected structured questionnaires. non-parametric Data employed both efficiencies investigated examined. result revealed that majority (81% ) farmers are male, (39%) fall within age range 36-40...

Microbiological processes were used for chitin and chitosan production by Mucor circinelloides (UCP 050) grown in yam bean (Pachyrhizus erosus L. Urban) medium. The polysaccharides were extracted by alkali-acid treatment and structural investigations by X-ray diffraction, Fourier transform IR analysis, viscosity and thermal analysis by TG, DTG, and DTA were done. The highest biomass yield (20.7...

African yam bean (Spenostylis stenocarpa) protein isolate was hydrolyzed with pancreatin (was purchased from sigma chemicals, St Loius Missouri, USA) to obtain an hydrolysate that has (42% degree of hydrolysis), which was characterized for its amino acid composition and ability to scavenge free radicals. The African yam bean protein isolate and hydrolysate samples were dried to constant weight,...

In recent years, there has been growing interest in the association between the residential environment and health. The association between residential environment (i.e., geographic elevation) and bone status is unknown. Furthermore, these associations could differ by exercise habits due to the chronically greater daily activity caused by steep slopes in mountainous areas. The aim of this study...

The Youth Anxiety Measure for DSM-5 (YAM-5) is a new self- and parent-report questionnaire to assess anxiety disorder symptoms in children and adolescents in terms of the contemporary classification system. International panels of childhood anxiety researchers and clinicians were used to construct a scale consisting of two parts: part one consists of 28 items and measures the major anxiety diso...

Field experiments were conducted at Ebonyi State University, Faculty of Agriculture Research Farm Abakaliki, Nigeria during 2009/10 growing seasons to evaluate the effects of staking and planting dates on the grain/tuber yields of seven accessions of African yam bean (Sphenostylis stenocarpa, Hochst. Ex. A. Rich). The results indicated that all the African yam bean accessions performed better w...

Discovering correspondences between schema elements is a crucial task for data integration. Most matching tools are semi-automatic, e.g. an expert must tune some parameters (thresholds, weights, etc.). They mainly use several methods to combine and aggregate similarity measures. However, their quality results often decrease when one requires to integrate a new similarity measure or when matchin...
