Growth and Performance as affected by inclusion of Moringa oleifera leaf meal in Broiler chicks diet

The experiment was carried out to investigate the inclusion of Moringa oleifera leaf as feed additive in broiler chicks. Eighty Anak 2000 Strains of two weeks old were allotted to four treatments with five replicates of four birds each in a completely randomized design. Four different diets with metabolizable energy levels ranging from 2800 to 2900kcal/kg diet were formulated and fed to the chicks for a period of four weeks. The level of inclusion of Moringa oleifera leaf meal ranged from 0% which served as the control, 1%, 2% and 3% in the diet. Inclusion of Moringa significantly (P < 0.05) enhanced weight gain of birds at 2% level of inclusion. The inclusion of Moringa did not significantly (P < 0.05) enhance feed intake and feed conversion. Keywords: Broiler chicks, Moringa oleifera, growth, feed intake, feed conversio

Strain improvement of Aspergillus flavus for enhanced ascorbic acid production by physical and chemical mutagenesis

The demand for ascorbic acid in the food and pharmaceutical industry led to the search for hyper ascorbic acid producing strains by physical and chemical mutagenesis. Spores of Aspergillus flavus were subjected to Ultraviolet (UV) radiation (240 nm) and Ethidium Bromide (EB) (25, 50, 75 and 100 μg/ml) to develop hyper-producing mutants. The selected mutants were cultured in a liquid fermentation medium containing Brewery Spent Grain (0.6 % w/v) at pH range 4 - 8, temperature range 30 - 45 °C, agitation speed range 60 - 160 rpm for 96 h. Ascorbic acid produced was quantified by titration techniques and with High Performance Liquid Chromatography (HPLC). The UV and EB mutant strains of A. flavus gave increased ascorbic acid yields of 6.99 g/L and 7.28 g/L respectively when compared to the parental strain with ascorbic acid yield of 3.92 g/L. Optimum ascorbic acid yields were produced at 40 °C, pH 5.0 and 100 rpm at 96 h of fermentation. This study shows the potential of strain improvement for enhanced ascorbic acid production.Keywords: Ascorbic acid; Ethidium bromide; Ultraviolet radiation; Aspergillus flavus; Mutagenesi

The Pedagogy Of Creative Arts Through Appropriate Strategies

Art education remains an academic illusion until, the return of Onabolu in 1922 to Nigeria after his training abroad. Onabolu, a man highly respected by both his country and Europeans alike, officially introduced formal art teaching to Lagos schools.1 He equally used his portraiture to immortalize Nigerian men, who took part in the Africa struggle.

Managerial learning and management development in New Zealand SMEs

Objectives: Managerial capability in New Zealand SMEs has been perceived by policy makers as a factor that has constrained SME growth and development (MED, 2008). The New Zealand Centre for SME Research (NZSMERC) has undertaken a programme of research on managerial capability in New Zealand SMEs. This paper reports findings from the Centre’s 2009 annual survey of 1500 SMEs, the BusinesSMEasure. The survey builds on a previous qualitative study and is part of a programme of research which had the following objectives: (1) to understand how SME owner-managers assess their development needs and how they meet these needs; (2) to assess the extent of participation in management development; and (3) to assess the perceived impact of management development on their business. Prior Work: Previous literature and research evidence with SME owner managers suggests a low take up of formal managerial development programmes and a reliance on incidental and informal managerial learning processes (Massey et al, 2005). NZSMERC’s previous qualitative study with 25 SME owner-managers (Battisti, et al, 2009), enabled the development of a conceptual framework and typology to explain orientation to learning and management development. Further, it allowed the identification of variables that affected attitudes to managerial learning and participation in management development. The survey has enabled the testing of some of the propositions from the qualitative stage, such as the importance of sources of managerial learning and the importance of variables that influence owner manager participation in management development. Approach: The 2009 BusinesSMEasure survey involved 4,165 firms (including 694 firms who responded in the 2007 and 743 firms who responded in 2008 survey). There were 1447 usable responses after excluding 297 ineligible and unreachable firms, which gave an overall response rate of 35%, Building on the previous qualitative study and utilising the adapted theoretical framework, we have applied non-parametric analysis to examine the significance of SME profile characteristics affecting against typologies of learning and management development. Exploratory factor analysis has been undertaken on the range of variables affecting managerial learning and development to reveal clusters of variables driving managerial learning and development. Hypotheses generated by literature and theory have been tested and regression modelling completed. Results: Survey findings suggest incidental and informal managerial learning processes were predominant modes of owner-manager learning. These types of learning were associated with practice-based and proximal sources of learning, as opposed to more distal sources. Significant variables that affected the type and sources of SME managerial learning were gender, age, learning orientation and a belief of self improvement. There was a strong link between innovation and engagement in management development. Firms with at least one type of innovation activity reported to be more engaged in management development across all three types of learning i.e. incidental, informal and formal. Theoretical developments in the literature are used to provide the basis for testing hypotheses associated with learning orientation and belief in self improvement Implications: The research undertaken by the Centre was driven by a policy imperative: to investigate the causes of an underlying trend in New Zealand SMEs which suggested that there was a lack of managerial capability in SMEs and a failure of SMEs to engage with formal management development initiatives. Having revealed the drivers of managerial development and sources of learning we develop implications for supply side management development programmes and policy interventions

An exploration into teachers' pedagogical content knowledge (PCK) for teaching quadratic function in grade 10

The study’s purpose was to explore the components of pedagogical content knowledge (PCK) for teaching quadratic function in Grade 10 mathematics classrooms in Mogalakwena district, Limpopo. The study was mainly guided by Shulman’s PCK and it was categorised as content knowledge, knowledge of the curriculum, knowledge of learners and knowledge of teaching strategies. The researcher employed a qualitative case study research design to explore the teaching of three purposefully selected Grade 10 mathematics teachers regarding their knowledge of quadratic function, strategies employed to teach quadratic function and knowledge of Grade 10 mathematics learners in quadratic function. In this study the researcher argued that PCK strands are interwoven, and in order to teach mathematical concepts, such as quadratic function, effectively teachers should employ components of PCK to complement one another. Data were gathered by lesson observation and interviews. Findings revealed that concepts of quadratic function are inefficiently addressed in Grade 10 due to teachers’ lack or inadequacy in some aspects of PCK. Therefore, there is need to develop mathematics teachers’ PCK in the Mogalakwena district to enhance their teaching of Grade 10 quadratic function.Mathematics EducationM. Ed. (Mathematics Education

Representation theory of algebras related to the partition algebra

The main objective of this thesis is to determine the complex generic representation theory of the Juyumaya algebra. We do this by showing that a certain specialization of this algebra is isomorphic to the small ramified partition algebra, introduced by Martin (the representation theory of which is computable by a combination of classical and category theoretic techniques). We then use this result and general arguments of Cline, Parshall and Scott to prove that the Juyumaya algebra En(x) over the complex field is generically semisimple for all n 2 N. The theoretical background which will facilitate an understanding of the construction process is developed in suitable detail. We also review a result of Martin on the representation theory of the small ramified partition algebra, and fill in some gaps in the proof of this result by providing proofs to results leading to it

Social capital for knowledge management : the case of small and medium-sized enterprises in the Asia-Pacific Region

This article proposes a conceptual framework that explains that the social capital of a community shapes the innovation performance of small and medium-sized enterprises (SMEs) through knowledge management within the firm. The study\u27s significance stems from the unprecedented effort in explaining how community social capital matters in the innovation performance of SMEs, a departure from previous studies that have typically examined market-related or hierarchical social capital in the form of formal networks and directly linked them to a firm\u27s innovation performance without due regard for knowledge management within the firm as an antecedent of organisational innovation performance. The aim is to stimulate further thinking and empirical research on the subject of social capital of a community in the SME and/or entrepreneurial context.<br /

Couples’ Socio-Economic Characteristics: Determinants of Children’s Nutritional Status in Akure South Local Government Area of Ondo State, Nigeria

The aim of the study is to examine the socio-economic characteristics of couples as they affect the nutritional status of children ≤5 years of age in Akure South Local Government area of Ondo State, Nigeria. Multistage sampling technique was used to select 200 couples whose last two children were not more than 5 years of age at the time of the interview. The mean age of the fathers was found to be 39years while that of the mothers was found to be 32years; more than half of the fathers (53.5%) had up to a tertiary education, whereas about half of the mothers (47.5%) had up to secondary education. The result of the bivariate analysis revealed a significant relationship between fathers’ income and children’s nutritional status (p<0.05); so also a significant relationship was found between mothers’ age and children’s nutritional status. Further analysis using the logistic regression coupled with the forward stepwise regression further found fathers’ income as the best predictor of children’s nutritional status, while mothers’ age at first marriage was found to be the best predictor of children’s nutritional status
