The biocontrol of Listeria monocytogenes on fresh-cut tomato using nisin and organic acids was investigated. Fresh-cut samples inoculated with $10^8CFU/mL$ of L. monocytogenes, treated with nisin (5,000 IU/mL), a combination of nisin and organic acids (acetic and citric acids at 3 and 5% each), with chlorine at 200 ppm as a control, and stored for six days at 4, 10, and $25^{\circ}C$ were used to evaluate certain physicochemical qualities (pH, titratable acidity, soluble solid content, vitamin C content, and color). Nisin treatment significantly (p<0.05) reduced bacterial population by 1.91-3.07 log CFU/mL. Nisin-citric acid combination provided 2.65-3.29 log CFU/mL reduction, while nisin-acetic acid combination provided 2.93-4.15 log CFU/mL reduction. The control treatment provided <1-2 fold log reductions. Slight variations in physicochemical properties of fresh-cut tomato were observed. Nisin and organic acids can be used to improve the microbial safety of fresh-cut tomato.
Religious Creativity and the Patronage of Sacred Places: A Case Study of Yoruba Religion
David Oladunjoye Alabi 한국외국어대학교 아프리카연구소 2022 Asian Journal of African Studies Vol.- No.52
The emergence and history of Christianity were painted with obvious characteristics of spiritual creativity, religious inculturation, adaptation and reformation. One positive contribution of religious creativity in the history of African Christianity since there has been shift in the center of gravity of the Christian religious atmosphere from Eurocentric to Afro-centric platform is the creation and patronage of sacred places in Africa. It has been a religious tool for both expansion of Christianity and conversion of non-Christian adherents into African Christianity. This has brought cultural conversion, inculturation, adoption and religious adaptation to African Christianity. Sacred places and their patronage are as old as the religion itself in human history. The ancient people had the notion that their gods dwelt in super sensible and unusual places around them and worshipped them from these places. Unique ponds, lakes, streams, rivers, lagoons, seas, grounds, sites, precincts, territories, caves, stones, trees, rocks, hills and mountains were considered as abodes of gods. Africans also considered this in their cultural and religious practices before the advent of Christianity in their land. Hence, African converts to Christianity had the carryover of this religious conception and it has influenced and altered the trends of creativity in African Christianity. Therefore, this paper addressed the value of religious creativity, especially from the patronage of sacred places in African Christianity. The negative effects that emerged due to the proliferation and patronage of the sacred places were highlighted. In conclusion, it recommended that the force of creativity in African Christianity should be biblically focused, culturally sensitive and the limits determined in order to avoid religious syncretism in African Christianity.

Comparative Study of E-Learning Experiences: A Case Study of Nigeria, South Africa and United States

We are in a society where availability of open courseware and countless internet-based online programmes are run by universities across the globe. The world is moving from the traditional face-to-face classroom teaching to a virtual classroom. There are concerns however; that this paradigm shift is limited by the understanding on what quality/standard is needed for a good e-learning resource. This concern has prompted the need to compare e-learning experiences in United States, South Africa and Nigeria so as to encourage developing countries to improve on this innovative approach to learning.
