Abstract:
Liquidity of a manufacturing firm means a lot for it provides a cushion that would enable the company to survive a period of low earnings during which the company might be unable to access capital. Studies, both theoretical and empirical, demonstrate that a firm's financial structure affects the firm's liquidity. However, as a corporation liquidity desires are mainly impacted through the character of its operations, a corporation liquidity call for will range relying on its unique circumstances. Specifically, the look at was looking to; discover the impact of brief time period debt, long time debt capital and equity capital on liquidity of manufacturing corporations indexed in Nairobi Security Exchange, Kenya.The usage of corporation size forms the moderating factor/ variable.

Abstract:
Functionally graded materials (FGMs) are categorized as functional composites, where the volume fractions of two or more materials change continuously based on position along specific dimensions (mainly through-the -thickness) of the structure to achieve desired functionality. A typical example of FGM is an inhomogeneous composite consisting of distinct phases of material constituents (e.g., ceramics and metals for thermal barrier structures), featuring a strong bending-stretching coupling effect. The overall properties of FGMs are unique and distinguishable from the individual materials comprising them. Mechanical properties exhibit continuous variation across the plate thickness. Variations in constituent volume fractions lead to diverse microstructures. The effective properties of FGM plates are assumed to change along the thickness direction, following power law, sigmoid, and exponential distributions. FGMs are created by altering chemical composition, microstructure, or design features from one end to the other as required. They exhibit high-temperature resistance, efficiently mitigating thermal stresses and moisture impacts. The variation in volume fraction throughout the thickness is computed using different homogenization techniques, namely the rule of mixtures, Mori-Tanaka scheme, and self-consistent method. Several micromechanical models have been developed and utilized to estimate effective properties of these materials in relation to volume fraction distributions. The manipulated variable concerns the concentration of reinforcing particles at various points within the component. This study delves into various methods and theories for modeling and analyzing functionally graded materials, offering a comprehensive exploration of their features. The outcomes and new findings of this analysis are presented.

Abstract:
The increasing prevalence of one-parent households and the necessity to study the effect of single parenting on children is evident. There have been numerous observable differences between children in single parent and two-parent households and one of most significant impairments is that of self-esteem. Self-esteem refers to an individual’s perception of self, their capabilities and worth. Divorce, separation, and widowhood disturb the family structure and during the fragile period of adolescence, the impacts are particularly severe.

Abstract:
The rapid advancement of technology has revolu- tionized the way we navigate and explore our surroundings. Traditional map-based navigation systems have been effective for outdoor spaces, but they often fall short when it comes to navigating complex indoor environments such as shopping malls, airports, and museums. Additionally, relying on visual interfaces can be challenging for individuals with visual im- pairments or those who prefer a hands-free approach to navi- gation.

Abstract:
Three different versions of hybrid ring couplers are proposed in this paper. The first one is an improved version of an old distributed coupler. The other two couplers are broadband lumped-distributed hybrid ring couplers. Theoretical analyses, simulations, and practical measurements are covered in this paper. Moreover, the theoretical results are almost matching with the practical results, so these couplers are almost fully corresponded with the theoretical results. All designs and simulations are implemented by the Advance Design System (ADS) software.

Abstract:
A variable lumped-distributed branch line coupler with three selected coupling levels is designed and proposed in this paper. This variable coupler combines three separate couplers. Each coupler has its own coupling level and bandwidth. The first coupler is a distributed, and the second and third couplers are lumped-distributed. A comparison between simulated and practical results is covered in this study. Minor and ignorable differences between the simulated and practical results are found, so this coupler closely aligns with the theoretical results. Moreover, 3D designs and fabrications are executed and included in this paper. Circuit designs and their simulations are implemented using the Advance Design System (ADS) software.

Abstract:
Partograph is graphical tool presentation of key data during the progress of labor. The observations of the mother are interpreted by a midwife or an obstetrician to make conclusions to whether the condition of the mother and fetus is fine. A woman from developing world is 100 times more probable to die during pregnancy or child birth than a woman from a developed country. The purpose of the study is to develop a model to promote partograph utilization by midwives during management of mothers in labour in selected hospitals in Kenya so as to reduce Maternal Mortality rate related to delivery.

Abstract:
The risk of venous thromboembolism (VTE) during pregnancy is 4- to 5 times higher than it is in the non- pregnant condition. [1, 2] Deep vein thrombosis (DVT) and pulmonary embolism are the two signs of VTE (PE). While most publications claim that VTE can happen at any stage of pregnancy, research indicates that the first half of pregnancy is when it happens most frequently. Complications including pulmonary hypertension, post-thrombotic syndrome, and venous insufficiency are examples of DVT and PE sequelae.

Abstract:
Unsafe abortion refers to an abortion that is unclean or unhealthy, conducted by an incompetent or untrained birth attendant using improper procedures. According to the World Health Organization (WHO) (2011), an unsafe abortion is the termination of an unplanned pregnancy by incompetent personnel or in an atmosphere devoid of minimal medical standards, or both. [1] Many social, physical, and biological factors contribute to unsafe abortions and their related problems. A botched abortion may result in life-threatening consequences.

Abstract:
Election of leaders by the people is the aim of democratic procedures. An electoral system is designed to make sure that the results are uncontested in any way and that they reflect the choices of the majority of voters, giving elected officials legitimacy. This study objective was to assess the nation electoral process. Consociationalism, voting, and rational choice theories served as the foundation for this investigation. The researcher adopted a descriptive study design and employed both qualitative and quantitative techniques. The research was carried out from July 2022 to December 2022. Political parties, political analysts, IEBC members, legislators, and voters made up the study target population. The researcher employed the stratified random sampling technique. The strata were created by the target demographic, and a random sample was drawn from each stratum. The researcher used interview guide techniques to collect data, using items that were developed from the study objectives and research questions. Questionnaires and interviews were the two main ways that data were gathered. Voters were handed questionnaires, and interview guidelines were provided for political experts, electoral experts, and IEBC officials. The information gathered through the use of questionnaires was analyzed using descriptive statistics. According to the results, Kenya electoral system is based on the plurality/majority system known as the First Past the Post concept. It is based on the Kenyan Constitution of 2010 and includes a wide range of actors, each of whom has a specific duty outlined in the Constitution. The IEBC is a key player among these parties. The report recommends, among other things, looking at alternative choices including mixed member and proportional representation models since they are more inclusive and produce fair representation as a remedy for the existing polarizing plurality voting system.

Abstract:
This research sought to determine how capital structure affected the financial performance of Kenyan listed energy and petroleum industry firms. The study main objectives were to determine how debt financing affected the financial performance of listed energy and petroleum sector companies in Kenya and how equity financing affected financial performance of listed energy and petroleum sector firms in Kenya. The theories that served as a guide for the study were: Pecking order theory and trade-off theory. This study adopted a correlational research design while dealing with the research objectives. A census method was adopted for purposes of analyzing the audited financial statements that were downloaded from the firm websites in arriving at detailed and well informed conclusions by employing Multiple regression, Correlation and Analysis of Variances techniques using the Statistical Package for Social Sciences (SPSS) software version 26 to establish the existence (or lack of it) of the study link between the dependent and independent variables. The study conclusions showed that the independent variables had a statistically significant effect on the financial performance of Kenyan listed energy and petroleum companies. The model correctly predicted the association between the variables based as depicted by the F-test. Recommendations on the variables were made for management consideration for future decision making where the study majorly recommended that the firms should use more internal equity to grow profitability as it does not involve costs of acquisition compared with external equity and debt finance and that in cases where external financing is required, management should base decisions on the finance option with the lowest investment risk and proportional costs.
