Effect of Neem (Azadirachta indica) Leaf Coating on Shelf Life and quality Retention of Tomato (Solanum lycopersicum L.) Fruits during Storage | Chapter 12 | Current Trends in Food Science Vol. 1

Tomato (Solanum lycopersicum) is one of the most important vegetable crops in the world. Effect of Neem leaf coating on the shelf life and quality retention of tomato fruits during storage was investigated. Three varieties of tomato fruits (UTC, Shase and Hoozua) obtained from Wurukum market in Makurdi were treated with Neem leaf coating to extend their shelf life and maintain their quality during storage. Significant variations were observed among the varieties in relation to most of the parameters studied. Irrespective of treatment, weight loss, postharvest decay, marketability and firmness decreased with increase in storage duration. Temperature ranged from 28.43 – 31.89°C. For weight evaluation, UTC ranged from 4.95 – 45.28, Shase ranged from 4.40 – 45.16 and Hoozua ranged from 4.62 – 59.48. Among the three varieties, UTC and Shase showed lower postharvest decay of 0.00 – 10.00 than Hoozua with postharvest decay of 1.00 – 10.00 and the lower postharvest decay was found in the treated fruits. Marketability ranged from 10.00 – 0.00 for all varieties and firmness ranged 4.00 – 2.00 for all varieties. Comparatively, all varieties treated with Neem leaf powder had same shelf life of (22.0±0.00) days, while control fruits of Hoozua variety produced the least shelf life of (15.0±0.00) days and UTC control fruits produced the highest with (19.0±0.00) days. Four fungi namely Aspergillus niger, Fusarium oxysporum and Botryodiplodia theobromae were isolated from the decaying tomato fruits. The findings of this research indicate that powder from the leaf of Neem plant can be used to extend the shelf life and maintain the quality of tomato fruits beyond their known natural limits.

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.

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

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
