Abstract:

Pipe transportation is the process of sending liquid to end users from production point. Many works on pipeline transportation has been in existing for decade but most of the works were concerned with the transportation without giving regard to problem encountered during the transportation. In Nigeria transportation of gas was done through tankers because the use of pipeline has not been used in the gas distributions. This institutional based research proposal will shade more light on pipeline transportation its importance and problems associated with it. In considering the problems a one-dimensional homogeneous model which represents a system of partial differential equations to describe mathematically the transient gas flows in a pipe. The governing equation was solved using Implicit Steger-Warming flux vector splitting method. The method has the capability of taken care of any flow that involves propagation especially pipe flow system. The result of this work will served as a way forward for implementing gas transportation in Nigeria and in due course Zamfara since it is a mineral resource producing state, it is hope that there will be time gas reservoir will be discovered in the state.

Abstract:

This study investigated the impact of marriage contract type (Statutory and Customary) on divorce likelihood in Rivers State, Nigeria. Data consisting of Demographic, Socio-economic and Treatment related variables were collected from Judiciary High court and Customary court for a period of 10 years for the analysis. The Factors estimated using survival analysis techniques were; Age at Marriage of Husband and Wife, Presence of Children, Duration of Marriage, Employment Status of Husband and Wife, Educational Level of Husband and Wife, Number of Counseling Sessions and Court Sittings attended, as well as marriage type. The Cox PH model revealed that marriage type does not influence the rate of divorce among couple in Rivers State. For Statutory marriage, significant determinants of divorce includes: duration of marriage (p = 0.000), employment status of husband (p = 0.028), and Presence of children (p = 0.045). For Customary marriage, significant determinants of divorce includes: presence of children (p = 0.018), and number of Court Sittings (p = 2.83e-06). Ironically, the result revealed that the presence of children increases the risk of statutory marriage divorce by 72% and reduces the risk of customary marriage divorce by 41%. The findings of this study using Pearson chi-square test for independence between the two types of marriage showed that chi-square statistic value χ2 = 0.0066 and the p-value = 0.936, indicates that divorce is independent of type of marriage contracted. This means that there is no relationship between the type of marriage contracted in Rivers State and the likelihood of divorce. Overall, this study contributed to the understanding of divorce likelihood in Nigeria, highlighting the complexity of factors influencing marital stability. The study thereby recommended among others that policy makers should focus on addressing socio-economic factors influencing marital stability.

Abstract:

The rate of unwanted pregnancies and maternal morbidity can be significantly reduced by the use of various forms of contraception. This study assesses the perception, knowledge and use of contraceptives among women in Ikot Abasi local government area of Akwa Ibom State. A pre-tested, structured interviewer-administered questionnaire was the tool for data collection and multi-staged sampling technique was used to select 512 females of reproductive age from the five clans of Ikot Abasi. The method of multinomial logistic regression were used to determine the contraceptive methods and determinants of contraceptive use while the Chi-Square test were applied to determine the perception of contraception. The results revealed that about 97% of the women have knowledge about contraceptives and their major source of information about contraceptives were from their friends/relatives which account for about (37%). Women in the age category 33 – 38, M.Sc/Ph.D level of education and income earners of more than ₦100,000 per month have high relative risk ratio of contraceptive use of 3.90, 2.48 and 3.32 respectively. Finally, Age group, level of education, level of income per month and relationship status were discovered to be the main determinants of contraceptives use among women in Ikot Abasi.

Abstract:

This study examines the transverse displacement and rotation of a prestressed damped shear beam supported by a Vlasov foundation when subjected to a moving load traveling at a constant velocity. The governing equations are expressed as coupled second-order partial differential equations. To simplify these equations, the finite Fourier series method was employed, transforming the coupled second-order partial differential equations into a sequence of coupled second-order ordinary differential equations. Subsequently, the simplified equations that describe the motion of the beam-load system were solved using Laplace transformation in conjunction with convolution theory to obtain the solutions. The effects of some pertinent structural parameters on the transverse displacement and rotation of a prestressed shear beam when under the moving load were illustrated in graphs. Notably, the graphs indicate that an increase in these pertinent structural parameters reduces the transverse displacement and rotation of a prestressed shear beam when subjected to the moving load. From a practical standpoint, increase in the values of these structural parameters significantly enhances the stability of the beam and increases the critical speed of the dynamic system, thereby minimizing the risk of resonance and ensuring the safety of the structure's occupants.

Abstract:

The paper provides a comprehensive cointegration analysis of the FDI inflows and economic growth in Nigeria by assessing the economic relationship between the FDI inflows, the real GDP, Inflation rate and Unemployment rate between the periods 2015 to 2022 (representing the administration of Former President Buhari). All the utilized data were sourced from Central Bank of Nigeria (CBN) Statistical Annual Bulletin except for Unemployment rate which was sourced from National Bureau of Statistics (NBS) Labor Force Report 2022. The data comprised of time series variables namely FDI inflows, real GDP, Inflation Rate and Unemployment Rate of Nigeria. The data were quarterly time series and cover the periods of 2015 to 2022. Different analysis methods such as descriptive analysis (i.e. time series plots and summary statistics), the Mann-Kendall trend test, Johansen cointegration test, Augmented Dickey–Fuller (ADF) stationarity test, Granger causality test, autoregressive distributed lag (ARDL) model and variance decomposition analysis (VDA) were employed. The empirical findings from the Mann-Kendall test results revealed significant decreasing trend in the FDI inflows. The findings infer MNCs investment in the country significantly dropped over the period. Furthermore, empirical findings from the Johansen cointegration results affirmed significant cointegration (i.e. causal relationship) between at most three (3) of the considered variables. Specifically, the Granger Causality results found the FDI inflows to significantly granger-cause (i.e. economically impact) the real GDP and vice versa, the unemployment rate to significantly granger-cause the RGDP and the FDI inflow, as well as FDI inflows to significantly granger-cause inflation rate. Consequently, empirical findings from the ARDL and VDA analysis significantly established long-run causal relationship between FDI inflows and RGDP (the economy growth). Explicitly, the results found the FDI to significantly negatively impact the RGDP both in the short-run and long-run. As well as, the RGDP was found to significantly negatively impact the FDI inflow both in short-run and long-run. Thus, the study concludes FDI inflows in Nigeria have been poor and not been encouraging over the years and consequently the FDI had demonstrated to significantly and negatively impact the economy growth of the country in short-run and long-run. The study therefore recommends that the current government of President Bola Ahmed Tinubu should direct more investment into agricultural production, build road networks as well as improve transportation system in order to ensure significant drop in inflation in order to boost the productive capacity of MNCs investors, so that more direct foreign investors can come into the country.

Abstract:

Finite transitive groups could be extended through points, lines or block as such geometric constructions were motivated through the concept of the Steiner system. The transitive extension of finite groups indicated the degree of homogeneity either by the partitioning of the groups or observing the orbits. We employed a different approach to the previous work carried out.

Abstract:

The nilpotentcy class for the Frobenius was determined based on the structure theorem. The socle of the groups were observed to be regular normal and elementary abelian such features were the conditions for the nilpotency classes, as they were the basis on which the socle of these groups constructed were nilpotent of some classes or order. The socle of the nilpotent groups whose structures is in conformity with D were classified based on the classification scheme for the finite primitive groups in relation to socle type.

Abstract:

Transitive groups were studied basically based on the idea of near field. The article mainly considered Dickson near field to construct groups which are 2-transitive..To achieve the result some restrictions were observed in relation to the near field. The research went through the constructions with the help of the classification scheme for finite primitive groups proposing that the subgroup is the stabilizer of the group. The idea of this constructions has relevance in coding theory.

Abstract:

This paper discussed Nash Equilibrium relative to political competition in most political parties in Delta State. Emphasis was placed on the understudy of the political competition between major political parties in 2023 Governorship Elections in Delta State using Nash Equilibrium. This work uses the Prisoner’s Dilemma-Non-Cooperative approach of games theory to extensively examine the political competition in parties using Nash Equilibrium. The importance of a free, credible and transparent electioneering process devoid of violence cannot be over-emphasize as it guarantee smooth transition from one democratic dispensation to another. Data collection that aided this research work sourced through interview and from the website of Independent Electoral Commission (INEC), the electoral arbiter tasked with the responsibility conducting elections into various positions in Nigeria. This paper was developed to understudy the Political Competition Between Major Political Parties in 2023 Governorship Election in Delta State Using Nash Equilibrium.
