Comparative Evaluation of Some Nutrient Contents and Antifungal Properties of Ground Musa paradisiaca (Plantain) Peels and Leaves | Chapter 06 | Advances in Applied Science and Technology Vol. 7

Musa paradisiaca (plantain) fruit peels and the plant leaves may have some nutrients and antifungal properties. Thus, the study determined and compared some nutrients (minerals and vitamins) in the ground plantain peels and leaves and the antifungal property of the aqueous and ethanol extracts (at concentration of 100 mg/ml) of the ground plantain peels and leaves, using standard methods. In either sample, vitamin A was not detected. The difference (±5.28 mg/100 g) in the highest of the detected vitamins, vitamin C in the samples, was statistically significant (p<0.05) whereas the difference (±0.01 mg/100 g) in the least detected vitamins, vitamin B2, was not significant (p>0.05). Out of the determined minerals (mg/100 g), the highest concentration was potassium (40.00 ± 0.08) in the plantain leaves followed by phosphorous (36.00 ± 1.65) in the plantain peels while the least was magnesium (1.80 ± 0.05) in the leaves followed by iron (5.60 ± 0.06) in the peels. The ethanol and aqueous extracts of the peels and leaves showed activity (inhibition zone diameter measured in millimeter, mm) against Candida albicans, however, the activity of the ethanol extract of the leaves (15.67±0.58) was higher (p<0.05) than that of the ethanol extract of the peels and the aqueous extract of the peels and leaves. The difference in activity against C. albicans between the samples extracts in terms of either the same or the different extracting solvent was significant (p<0.05) but the overall difference between the samples compared to the extracting solvents (±0.67) was the same hence non-significant (p>0.05). A similar trend was recorded for the activity of the ethanol and aqueous extracts of the peels and leaves against P. notatum. Thus, the plantain peels and leaves could be alternative source for vitamin C. The extracts (aqueous and ethanol) had activity against C. albicans and P. notatum hence may be useful in managing such pathogen-induced ailments. Overall negligible difference in activity against either C. albicans or P. notatum in terms of samples and the extracting solvents was suggested and this may be an underlying useful trend for comparing the overall antimicrobial activity of different samples and solvents, hence warrants a follow up.

Empowerment and Leader Member Exchange towards Organizational Citizenship Behavior Readiness among Government Workforce in Malaysia | Book Publisher International

  State agencies are among the most significant entities that represent the public's needs, and their programmes are essential to a state's and the nation's economic growth and development. State agencies have been rife by public concerns for years, as demonstrated by the Public Complaints Bureau, as problems of inefficiency in service quality and delivery have yet to meet the public's standards. With the support of 15 employees from state agencies on Malaysia's east coast, this study aims to achieve three targets. The first and second objectives are to investigate the ties between leader-member exchange (LMX) and OCB empowerment. The final aim is to define the most significant factors that affect OCB willingness. A total of 288 people took part in the survey, which was conducted using a cluster sampling process. The survey items had achieved the necessary reliability, according to the pilot test results, and some sub-dimensions were renamed after factor analysis.

The Utilization of Agro-Waste: A Nanobiotechnology Point of View | Chapter 10 | Recent Advances in Biological Research Vol. 5

Aims: To review the utilization of agro-waste in the eco-friendly synthesis of nanoparticles and their biomedical, catalytic and industrial applications. Study Design: A review. Place and Duration of Study: This review was carried out in the interim of three weeks exploiting all relevant data, literature and publications where necessary. Methodology: Profound gathering of literatures/publications and reviews were employed with all carefulness and professional courtesy; enough useful information were gathered over time. The introduction emphasizes the dawn of science and technology, when great ideas were still latent later leading to the advent of history changing innovations like the completion of human genome and then the birth of nanotechnology. Although, nanotechnology had been known decades been popularized by Richard Feynman in his talks in the year 1959; and in this present dispensation, nanotechnology has been a solution to many intricate challenges/ t

Re-asserting Cultural Perspectives: Old People and New Ideas in Bole Butake’s Lake God and The Survivors and Sankie Maimo’s Succession in Sarkov | Chapter 10 | Perspectives of Arts and Social Studies Vol. 2

African cultures have undergone transformations from the colonial period to the present, often to the detriment of its cultural evolution and within the larger global community. As it were, colonial education subordinated African communalism and created in its place an anti-African spirit evident in the assimilation of western values. This did not only end up in a kind of cultural betrayal, but also posed as a serious threat to the dignity and identity of the people. Those who fall prey to this kind of cultural imperialism are the young people who are often irrationally carried away by western fashion and modes that they tend to neglect and/or forget their cultural ways of life as they join the race of “progress.” This situation has given rise to a conscious effort by creative writers to re-assert and protect African values while at the same time liberating themselves from the longstanding western effort at suppressing, controlling and dominating their thoughts particularly through n
