ANTIMICROBIAL ACTIVITY OF MAGNOLIA OFFICINALIS EXTRACTS IN VITRO AND ITS EFFECTS ON THE PRESERVATION OF CHILLED MUTTON  

British Library Electronic Table of Contents (United Kingdom)

Abstract The inhibitory effect of the extract from Magnolia officinalis (MOE) against L. monocytogenes, S. faecalis, E. coli, S. typhimurium, S. aureus and B. anthracis by paper-diffusion methods and the characterization of the mutton immersed in different concentrations of the MOE during storage were evaluated in this paper. The results showed that MOE could significantly inhibit the growth of S. aureus, S. faecalis, B. anthracis and E. coli, and their MIC was 0.02-mg/mL, 0.03-mg/mL, 0.05-mg/mL and 0.10-mg/mL, respectively. MOE showed weak inhibition for the S. typhimurium. The mutton treated with 2%, 4% and 6% MOE resulted in suppression in the increase of total volatile base nitrogen, thiobarbituric acid reactive substance, and the growth of Enterobacteriaceae, Pseudomonas. The cooled m...

Studies on thermal degradation and termite resistant properties of chemically modified wood  

Energy Technology Data Exchange (ETDEWEB)

A series of experiments were carried out to examine the resistant capacity of a chemically treated hard wood, Anthocephalus cadamba (Roxb) Miq. to thermal and termite degradation. The treatment with thermosetting resins viz. urea formaldehyde (UF), melamine formaldehyde (MF) and phenol formaldehyde (PF) at 31-33 levels of weight percent gain (WPG) increased the strength property i.e. modulus of rupture (MOR) by 7.50-21.02% and stiffness i.e. modulus of elasticity (MOE) by 9.50-12.18% over the untreated one with no remarkable effect on specific gravity. The treated samples were found resistant to termite attack, while the untreated one was badly damaged by termites on 12 months' exposure to a termite colony. The thermal degradations of untreated and treated wood samples were studied using thermogravimetric (TGA) and differential thermogravimetric (DTG) techniques at heating rates 20 and 30 {sup o}Cmin{sup -1} in temperature range 30-650{sup o}C. The treated ...

Forum on Flexible Education. Reaching Nomadic Populations in Africa. Summary Report  

Science.gov (United States)

This report describes the Forum on Flexible Education: Reaching Nomadic Populations in Africa, which was held in Garissa, Kenya, from 20-23 June 2006. The objectives of the Forum were to share experiences and best practices, create linkages and encourage collaboration in order to make education more accessible to nomadic communities. Representatives from the Kenyan MOE, COL, ComSec and UNICEF provided remarks at the Opening Session of the Forum. They stressed the need to find ways to include nomadic children in the education process and the importance of developing alternative channels for the delivery of education and training. There were two keynote addresses. The first, from Professor Gidado Tahir, Executive Secretary of the Universal Basic Education Commission in Nigeria--presented by his colleague, Dr Salihu Bakari--focused on the realities of the nomadic lifestyle and educational strategies that have been effective. The second, by Dr. Nafisa Muhammad and ...
