The average household size in of goat was higher than that of other livestock species. A total of 40 woody plant species were identified in all study areas. Acacia karoo, Coddia rudis and Scutia myrtina were the most dominant woody species in all study areas. Most of the woody plant species had the highest abundance in the height class >0 - 1 m. The average total woody plant density in Thorn bush and Mixed bush were 3461 and 2416 number ha-1, respectively. In conclusion both study areas were highly encroached and it was also perceived by elder from both areas that bush encroachment is a problem in the rangelands.]]> Wed 12 May 2021 22:49:00 SAST ]]> Phytochemical, antibacterial and pharmacological investigations of Clausena Anisata (Wild).

The antioxidant and free-radical scavenging activity of the obtained oils and extracts were tested by means of 1,1-diphenyl-2-picrylhydrazyl radical (DPPH+) assay, [(2,2ˊ-azino bis-(3-ethylbenzothiazoline-6-sulfonic acid)] (ABTS), nitric oxide and ferric reducing power assays. The oils and extracts showed DPPH radical scavenging ability, but not as high as the standard drugs. The base extract showed a higher reducing power than the standard drug, rutin. There were significant differences in the phytochemicals contents of the various leaf extracts. The acetone extract has the highest flavonol, proanthocyanidin, and alkaloid contents. The ethanol extract showed the highest amount of phenolic content with the acid extract, having the least. Thin layer chromatography (TLC) and column chromatography was employed to obtain different fractions of extracts using four eluent solvent systems of varying polarities: toluene, petroleum ether, hexane and ethyl acetate and sprayed with anisaldehyde. A single, visible spot of B-fraction was developed, collected and analyzed as 1-methyl-2,4,5- trinitroimidazole with renown valuable properties.]]> Tue 15 Jun 2021 15:58:29 SAST ]]> Risk factors associated with developing asthma and tuberculosis: a case study of a hospital, Lagos Nigeria https://commons.ufh.ac.za/vital/access/manager/Repository/vital:39616 Tue 07 May 2024 11:15:41 SAST ]]> The electrical, structural and elemental analyis of degraded single junction amorphous silicon solar modules https://commons.ufh.ac.za/vital/access/manager/Repository/vital:39095 Tue 07 May 2024 10:47:22 SAST ]]> An investigation of source rocks and depositional environments on acid mine drainage in South African coal mines: a comparison of the main Karoo basin and sub-basins. https://commons.ufh.ac.za/vital/access/manager/Repository/vital:43139 Tue 07 May 2024 08:41:04 SAST ]]> Woody encroachment and plant-root soil interactions in a semi-arid savanna https://commons.ufh.ac.za/vital/access/manager/Repository/vital:39131 0.05), but there were significant differences in root biomass between grassland (HVU2) and thicket (HVU3) site (p<0.05).
