Physicochemical Properties of Some Vegetable Seed Oils and Their Applications | Chapter 06 | New Insights on Chemical Research Vol. 1

The physicochemical properties of oils were discussed, and as a case study, extracted from three locally available plant seeds in Nigeria namely: Alchomea cordiforlia, Cyperus esculentum and Irvingia gabonensis using n-Hexane and their properties determined. The results of the analysis revealed that their % yield were 37.00, 27.50 and 33.00 for A. cordiforlia, C. esculentum and I. gabonensis respectively. Their odour was non-offensive and their colours were reddish, light yellow and milky white for A. cordifolia, C. esculentum and I. gabonensis respectively, making them bright and attractive. The specific gravity of the oils at 25°c was 0.91, 0.94 and 0.92 for A. cordiforlia, C. esculentum and I. gabonensis respectively. Their flash points in °c were also 155, 159 and 229 respectively, indicating that I. gabonensis is the most thermally stable oil and suitable for frying. The chemical properties for A. cordiforlia, C.esculentum, and I. gabonensis respectively were as follows: Acid values in mgKOH/g were 24.67, 5.33 and 3.73. Peroxide values in mEqKg-1 were 7.26, 9.86 and 2.96. Saponification values in mgKOH/g were 162.13, 179.52 and 238.43. Iodine values in g/100g were 24.62, 11.68 and 3.38. These results indicate that the three seeds are viable sources of oil based on their % yield. They are good for both domestic and industrial use based on their acid, saponification and iodine values. Their properties in most cases compete favorably with palm kernel oil (PKO) which is currently being used for many domestic and industrial purposes in Nigeria especially for the making of paints, soap, cosmetics, lubricant and varnishes.

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
