Germination Response of Albizia lebbeck (L.) Benth Seed to Different Scarification Treatments in Botswana | Chapter 14 | New Perspectives in Agriculture and Crop Science Vol. 1

Evaluation of different pre-sowing treatments on germination of A. lebbeck seeds was conducted in the laboratory at Botswana University of Agriculture and Natural Resources (BUAN) from January to February 2018. The experiment was laid out in a completely randomized design (CRD) with five treatments as follows; mechanical scarification, boiling water, hot water, concentrated sulphuric acid (98.8%) and control (untreated seeds). Sulphuric acid had four different levels of exposure time (15, 30, 45 and 60 minutes), whereas boiling water had three levels of exposure time (1, 3 and 5 minutes). Each treatment had four replications. Germination percentages (GP), mean germination time (MGT) and germination index (GI) were calculated and the data were subjected to analysis of variance (ANOVA). Significant (p<0.01) differences in germination parameters were observed across the treatments. Concentrated sulphuric (60 minutes) had superior absolute numbers than the rest including the control, recording 82% compared to 8% for control. However, no statistical differences were observed across the three main treatments; all sulphuric acid, boiling water (1 minute) and mechanical scarification. The control revealed the longest MGT which was significantly (p<0.01) longer than the rest. As would be expected, pre-sowing treatments which outperformed others in terms of germination percentages recorded, significantly (p<0.01) increased the GI as compared to control. Based on these findings, mechanical scarification, boiling (1 minute) and hot water treatments are recommended as suitable seed pre-sowing treatments for enhancing the germination of A. lebbeck seeds because the methods are cheap and easy to perform. Although concentrated sulphuric acid yielded the best rest results the method is not recommended because of its high cost and the danger it poses to workers.

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
