Microbial Mediated Production of Bio-ethanol from the Rhizome of Imperata cylindrica (L.) P. Beauv. (Spear Grass)

Abstract: The microbial mediated production of bio-ethanol from the rhizome of Imperata cylindrica (spear grass) was carried out in this research work. Proximate analysis of the rhizome was done to determine the protein, carbohydrate, moisture, ash, lipid, and fibre contents. Sugar profile analysis was carried out using Gas Chromatography (GC). The sugars obtained from the rhizome include ribose, xylose, arabinose, rhamnose, fructose, glucose, maltose, lactose, and sucrose. Ethanol yield increased simultaneously from day 5 to day 20 for all reactors in six different experimental design i.e, Saccharomyces cerevisiae alone; Serratia marcescens alone, Aspergillus flavus + Saccharomyces cerevisiae; Apergillus flavus + Saccharomyces cerevisiae + Serratia marcescens; Aspergillus flavus + Serratia marcescens including the control (containing no microorganism). The highest ethanol yield was achieved at pH 7 and temperature range between 280C to 380C. The reducing sugar decreased from 0.37 to 0.03 g/mol as the period of incubation increased while cell density increased from 0.1 to 0.68 nm as the period of incubation increased. Reactor containing co-cultures of Saccharomyces cerevisiae, Serratia marcescens and Aspergillus flavus in combination produced the highest ethanol yield at day 20 while the reactor containing only Serratia sp produced the lowest ethanol yield. This study has demonstrated that the use of Saccharomyces cerevisiae, Serratia marcescens and Aspergillus flavus co-cultures is more effective in bio-ethanol production using I. cylindrica (spear grass) compared to individual cultures.

Educational management planners' scaffolding of model lead and teaching delivery strategy in secondary education

Abstract: Introduction We begin by domesticating scaffolding within the context of our discourse. Here is a process of enabling students to accomplish what is normally beyond their abilities. Scaffolding means providing help so students can succeed with a task that otherwise would be impossible. This is supporting students before, during and after they read. Here is a variety of literacy-related instructional strategies that assist content-area learning. The provided instructional strategies are designed for use by all content area teachers, as well as English language arts teachers, remedial reading and language arts teachers, literacy specialists and literacy coaches. They are designed for implementation by those teaching Basic 9 and above level of learners up to the Post Graduate stage. The instructional strategies presented are not reliant on extra texts, supplies or funding. . Variety is key. The instructional strategies are grouped by support for: comprehension, vocabulary, fluency and spelling. The provided instructional strategies should be used with diverse fictional and nonfiction texts; should be used before, during and after reading; should be used as preand post-assessments, and should be used with students independently, in pairs, in small groups and as a whole class

Corporate Characteristics and Influence on Share Based Payment of Financial Service Firms in Nigeria

Abstract: This investigates the effect of corporate characteristics on share base payment of financial service industry in Nigeria. Objective of the study is to if internal factors affects share base payments of corporate organizations in Nigeria. We analyzed five commercial banks and five insurance firms that are quoted on the floor of Nigerian Stock Exchange. Technique adopted for sampling adopted is convenience sampling. As the nature of data is panel therefore, pooled regression, fixed and random effect tests are run. Random effect results are focused after applying Hausman’s test. From the fixed effect model, tangibility, risk, management efficiency, debt equity ratio, corporate governance and cost of capital have negative but insignificant effects while return on investment, liquidity and firm size have positive and insignificant effect on share base payment. We conclude that corporate characteristics does not significantly influence share base payment of the selected financial service firms. We therefore recommend that the use of share base payment should be integrated with the corporate structure such as ownership structure, capital structure and others.

Servant leadership and organizational success of deposit money banks of rivers state, nigeria

Abstract: This empirical study investigated the relationship between servant leadership and organizational success in Deposit Money Banks in Rivers State. A sample size of 140 respondents which consisted of managers and supervisors was determined from a population of 220 respondents. The study adopted cross-sectional survey research design as it collected data from vast respondents. 140 copies of questionnaire were distributed and 122 copies were found useful for analysis. The questionnaire was analyzed using descriptive static while the study hypotheses were tested using Spearman’s Rank Order Correlation Coefficien t. The findings revealed that servant leadership components affect organizational success measures, and recommended that Management should develop the idea of empowering subordinates to enable continued growth of the financial institutions. Management should develop humility and show by example in order for subordinates to emulate their style of leadership as these would facilitate realizations of institutions continuous existence and growth. Management should ensure that their behaviour exerts positive influence on subordinates towards achievement of organizational success.

Thermal decay of an initially hot isothermal water body with application to thermal energy storage

Abstract: The thermal decay of an initially hot isothermal water body contained in a tank was studied. Analytical solutions (including a group-theoretic solution) were obtained for the one-dimensional heat conduction equation with heat loss from the sides of the tank. The convective heat transfer coefficient was assumed not to be constant over the surface of the tank but to vary with space and time. A very good agreement was obtained between the group-theoretic solution and a numerical solution using the Crank-Nicholson finite difference scheme. The analytical results are discussed in terms of the underlying physical mechanisms.
