One of the established traditions in Nigeria foreign affair is that each administration proclaimed it our foreign policy thrust in the light of long established one. The research, ‘concentric circles theory and Nigeria’s foreign policy 2015-2019’ was designed to identify president Buhari’s foreign policy thrust in the light of concentric circles theory. The research was guided by the following questions: what are the assumptions of concentric circle theory? What are the Nigeria’s foreign policies 2015-2019? And are Nigeria’s foreign policies 2015-2019 concentric? Content analysis due to the data sources was adopted. It discovered that concentric circles theory originated from sociology and in foreign policy making and analysis, some saw three while other four concentric circles. Nigeria foreign policy thrust were combating insecurity, tackling corruption and economic growth via job creation. It were recommended that: The four concentric circles should be used for Nigeria’s foreign policy making and implementation, The innermost should be well defined via the national or domestic needs and the domestic needs should be the guideline of commitment in regional, continental and global affairs.
Let G = (V ,E) be a simple connected undirected graph with vertex set V and edge set E. The advent of graph theory has played a prominent role in wide variety of engineering applications. Minimization of crossing numbers in graphs optimizes its use in many applications. In this paper, we establish a necessary and sufficient condition for semi-splitting block graph to have crossing numbers 1 and 2.
Automation is one of the major concerns in any industry today. Automation is encompassing virtually every Walk of life required right from agricultural to space technology. Plant Automation is the necessity for the Manufacturing industry to survive in today’s globally competitive market .It relates to the working of the system at all times without any human intervention. In this paper we are designing a control circuit for the automation of Gas Tunnel Kiln (GTK) using relay logics and Variable Frequency Drives (VFD's) because the present doors and the movement of the transfer car in and out of the kiln are being operated manually and the temperature of the kiln is very high and hence manual operation is not safe. As whole, the process of charging and discharging of the green Insulators is being automated. The first step towards this is designing ladder diagrams which can be implemented using hardware components and simulation is done using LADSIM - PLC Simulator.
Let G = (V ,E) be a simple connected undirected graph with vertex set V and edge set E. The advent of graph theory has played a prominent role in wide variety of engineering applications. Minimization of crossing numbers in graphs optimizes its use in many applications. In this paper, we establish a necessary and sufficient condition for semi-splitting block graph to have crossing number 3.We deduce a necessary and sufficient condition for semi-splitting block graph to have crossing number 1 in terms of forbidden subgraphs.
It is well known that the presence of stenosis in the artery is highly responsible for the changes of flow characteristics. Nevertheless, the dimensionless numbers especially the Reynolds number seems to play a pivotal rule in the change of flow characteristics. Therefore, a sophisticated blood flow model is required for sound explanation of the impacts of atherosclerosis and dimensionless numbers on flow properties. The objective of this study is to develop a mathematical model by combining the effects of stenosis and Reynolds number on blood flow properties considering blood as Casson’s fluid. The effect of stenosis height, Reynolds number, stenosis length and yield stress on the flow characteristics such as flow resistance, flow rate, pressure drop, skin-friction and axial velocity have been analyzed. We have found that the increment of stenosis height and length, and the diminution of Reynolds number are liable for the augmentation of resistance of flow. It has also been obtained that the flow rate and skin-friction are influenced by stenosis height. The results have been derived followed by the algorithm, developed numerically using MATLAB programming language. The graphical representations with suitable parameters have also been shown in the study for the better understanding.
This study investigates the moderating influence of Ghanaian national culture on the relationship between corporate governance compliance and profitability of Medium Scale Enterprises. It is an exploratory parametric research and collected data from 1010 with the aid of structured questionnaire. The study applied purposeful sampling technique, and anchored on stakeholder and institution theoretical frameworks. The study reveals that: (vii) Ghanaian national culture has 47% statistical significant moderating positive effect on the relationship between corporate governance compliance and the profitability of medium scale enterprises in Ghana; and (viii) Ghanaian national culture did not significantly moderate the relationship between compliance to shareholders rights, compliance to board responsibility, compliance to equitable treatment of stakeholders, compliance to transparent disclosure, and the profitability of medium scale enterprises in Ghana. This study would add to existing literature on corporate governance practices in developing countries; guide policymakers in their efforts to developing or revising principles of corporate governance practices for the Medium Scale Enterprises; and contribute to the progress of enhancing public understanding of corporate governance principles in general and that of Medium Scale Enterprises in particular
Single motherhood is now becoming a "norm," the number of single mothers has been steadily increasing for so many reasons such as giving birth outside marriage, separation, divorce, annulment, the death of a partner, or simply because some women chose to have a child and stay single. The study explored the lived experiences of single mothers in raising their children. Thus, the study aims to determine how single mothers cope with their situation to provide improved life to their children and themselves. The researchers have employed qualitative research methodology. The fundamental question is, what are the lived experiences of single mothers in child-rearing practices? The study's findings revealed that financial problems (struggles in meeting the basic needs of the children/family) and loneliness as the predominant feeling among single mothers are the common problems and experiences of being a single mother. Faith, support from family and community, and their job play an essential role in coping with their situation and helping them survive. It made them feel suitable for themselves, and they were trustworthy and independent in raising their children as single mothers. The study also suggests a need to recognize the struggles of single mothers and their children and call for interventions by both government and social workgroups to help them cope with single parenthood's financial, psychological, and emotional challenges.
This paper is aimed at investigating and describing the interference of Chinese Language (L1) students into written English texts (L2). The present study is limited to syntactic interference, such as lexical, phonological, and discourse interference. Qualitative data was collected from ten Chinese students. The data were analyzed by Miles, Huberman, and Saldana’s theory. The findings showed eight syntactic interferences occur in the English texts, for instance, the syntactic interference on parts of speech (noun, adjective, verb), tenses, pronouns, auxiliaries, articles (definite and indefinite), nouns indicating possession, noun plurality, and on impersonal ‘there’ as sentence subject. The interferences are found either in the L1 rule which is applied in L2 or in the deviation of L2 as its non-existence in L1.
