ABSTRACT

The goal of this work is to obtain tunneling probability of a gamma particle. The application of Schrӧdinger’s equation in barrier penetration has been applied to gamma particle decay for light, medium and heavy nuclei. Gamma particle tunneling probability has been calculated analytically. Decay probability computed for each gamma particle emitting nucleus shows interesting variations. Log plot of calculated Decay constant plotted against atomic number (Z), mass number (A) and Energy for gamma particle emitting nucleus shows the variations interesting.   Half-life which is a function of decay probability plotted against gamma particle energy or against atomic number of gamma particle emitting nucleus shows the variations of decay probabilities. Log plot of Calculated Half-life plotted against atomic number (Z), mass number (A) and Energy for gamma particle emitting nucleus shows interesting variations of decay probabilities. Calculated half-lives compared with experimental half-lives for each gamma particle emitting nucleus shows results which are in good agreement.

Key word: Schrӧdinger’s equation, Emission, Half-life, Gamma and Decay constant.

ABSTRACT

A bioremediation strategy based on Azotobacter- seeding of oil polluted medium containing indigenous bacterial degraders was used to enhance the removal of the contaminating crude oil. In this study, biological nitrogen fixation was co- optimized with crude oil degradation. Increase in cell number for both Azotobacter (from 0.5 – 4.3 x 106 cells/ml) and the oil degrading bacteria from 0.3- 0.6 x 106 cells/ml) in 10 days indicated significant nitrogen fixation and oil degradation in the two bacteria respectively. The low percentage, remaining crude oil (20 – 30%) in the polluted mixed cultures within 14 days confirmed the bioremediation efficiency of the bacterium-Azotobacter consortium. In the field demonstration of this bioremediation and Biological nitrogen fixation processes in an oil polluted soil microcosm, increase in growth parameters of the planted sorghum cultivar was significant in the Azotobacter – seeded plots, relative to non-seeded portion. Hence this bioremediation strategy hold strong potential for a large-scale clean-up of oil-polluted degraded soils and other ecosystems in the natural environment.

ABSTRACT

This paper examined media planning, mixing and application in Public Relations and Advertising practice. Today, society’s mode of communication has long moved from the traditional interpersonal communication to that of modern mass communication, where large heterogeneous and scattered audiences are the target. Organizations involved in the production of either goods or services also advertise as well as use public relations tools as a means of reaching their audiences. Core attention is focused on the various forms of media of advertising and public relations, the paper also reviewed concepts such as media, public relations and advertising. The information processing theory was used to properly anchor the paper. The paper concludes that media planning and media mixing are essential ingredients of the overall Integrated Marketing Communication (IMC). The paper recommends that organizations should engage more qualified PR and Ad practitioners, in order to bring innovative ideas on how the image of the organization and acceptability of their products or services could be boosted. Organizations should know that public relations is not a smoke screen to cover bad deeds, as a result of which they should not wait until there is a negative turning point before they do the right thing. Similarly, companies should not involve themselves in advertising bad products or services; rather, advertising should be used to promote marketability of their good products and(or) services.

ABSTRACT

This paper aims to conduct a critical examination of journalism ethics in Nigeria, especially in light of the emergence of modern media technology. It begins by arguing for an ethically grounded practice in journalism, particularly in light of the media’s roles as representatives of social realities. A critical examination of professional standards in Nigerian journalism, as well as the complexities of emerging media technology were also examined. This paper utilized a textual, secondary or desk research approach which involves the use of existing data in a systematic way; to call attention to the need for contemporary media practitioners in Nigeriato pay more attention to politics and still see the importance of their reports in terms of positively influencing Nigeria’s national development and progress. The paper therefore argued that it is important for the media to behave more ethically in order to close the reputation gap that has already been established. The paper concluded that Nigerian journalists must be aware of emerging threats and hegemonic trends of new media technology.

ABSTRACT

The study delved into TETFUND Applications in Infrastructural Development and University Leadership in Rivers State. The study adopted a descriptive survey design. The descriptive design will seek the opinions of respondents who will serve as samples representatives of the study group on staff development. The population of the study comprised of 570 university leaders (HODs, Deans, Directors, Principal officers, Professors, Senior Lecturers), drawn from Ignatius Ajuru University of Education, Port Harcourt, and Rivers State University. A sample size of 382, which makes up 20% of the population, was randomly drawn from the named institutions. The instrument for data collection in this study was a self-structured questionnaire titled TETFUND application in infrastructural development and University leadership in Rivers State (TIIDRU). Items on the questionnaire were structured on a four point rating scale ranging of Strongly Agree (SD) 4 points, Agree (A) 3 point, Disagree (D) 2 points and Strongly Disagree (SD) 1 point. The instrument was given to the researcher’s senior lecturers and professor in department of Educational Management of the University to make necessary correction and to validate the content of the instrument.The study adopted the Crumbach Alpha using SPSS version 23. The tested scores were correlated using the Crumbach Alpha at 0.9331> 0.71 which showed that the instrument was highly reliable. Mean and standard deviation was employed to analyse the research questions. The hypotheses were tested using the T-test at the .05 significance level. Out of the 382 copies of the questionnaires distributed, 370 or 97% were duly completed and returned.  The analysis was therefore based on the 370 returned questionnaires. The study found that there have been inadequate applications of TETFUND in university critical areas such as hostels, lecture halls, library, workshops and libraries and recommended for a refreshed trend of allowing redirecting and appropriating such funds to quality university infrastructure by university leaders.
