This study was undertaken to examine the nature and quantify the magnitude of Genotype by Environment interaction effects on rice (Oryia Sativa L.) grain yield and to determine the most stable and winning genotype (s) in terms of yield stability and performance in two rice producing hubs. The study was conducted at four locations within two rice producing hubs in Northern Ghana on fifteen (15) rice genotypes including a checking genotype GR18 red. A randomized complete block design with three...
The study focused on the assessment of stakeholders participation as a determinant for effective land use plans implementation in the Tamale Metropolis of Northern Region of Ghana. Primary data was then collected from households and institutions and analyzed. The study revealed that those factors such as leadership qualities, transparency, resources availability and centralization of decisions affect successful stakeholders’ participation in implementation of land use plans. The benefits of...
Breast cancer is the most frequently diagnosed cancer and the leading cause of cancer death in female's worldwide. The objective of the study was to identify and describe breast cancer survival pattern in Ghana and factors that explain the disparity in survival rates for breast cancer by the use of Cox proportional hazard. The extent to which selected demographic, hormonal and reproductive factors influence the cause of breast cancer were also examined using the logistic regression technique ...
Abstract Rearing chicken has contributed positively to global nutrition, especially egg production. This practice attracts both large and small-scale poultry keeping within the world’s economy. Egg storage has been a problem due to ineffective methods subjecting many farmers and egg retailers to losses. These methods include various models involving statistical analysis of the storage conditions on the egg quality. However, they do not provide sufficient information. Therefore, confusion p...
Inflation is one of the basic indicators of macroeconomic stability, influences numerous other macroeconomic factors and it debilitates the economy of the country. Thus, in this study, the major objective was based on modelling and forecast inflation in Ethiopia and its components using a VAR model. all five series exhibited an increasing pattern, indicating non-stationarity in each of the series. The analysis was based on annually data from 1992 to 2021, encompassing 30 years. The results in...
Abstract: One of the greatest challenges facing the people of sub-Saharan Africa is the production of sufficient food to feed a rapidly increasing population in the face of dwindling finances. As the population grows at 3% and food production at 2% per annum, an annual shortage of 250 million tons of food is expected by year 2020. The greatest obstacle to increasing the production of maize and sorghum, the staple food in many African communities south of the Sahara, is damage by phytophagous...
ABSTRACT The main objective of this study was to examine factors associated with childhood mortality and morbidity in South Sudan. The specific objectives were to establish childhood mortality, examine the effect of childhood factors on morbidity as well as examining the contribution of mother factors on childhood mortality and morbidity. The study used both descriptive and inferential analysis using secondary data from Second South Sudan household health survey (SSHHS2). Using univariate, ...

Abstract The study was set out to investigate the prevalence of the five-child killer diseases and its cause effect on under-five mortality. It was driven by four major objectives; Determining the prevalence rate of the five child-killer diseases; Determining the proportion of mortality due to the five child-lciller diseases to the total under-five mortality in the studying area; Examining the correlation between the five child-killer diseases and under-five mortality and Determining the caus...
ABSTRACT In this work, the seven-factor central composite design () is studied in respect of a pair of missing values using the minimax loss criterion. It was observed empirically that seven-factor central composite design with k = 7 , = 128 f n , = 14 a n , = 3 c n and n = 145 is robust at a = 2.6 and variance robust at a = 2.45. We also observed that the loss effect of missing a pair of factorial points is a decreasing function of increasing a , while the loss effect of a pair of axial poin...
Abstract In this work,we applied an Integer Programmingapproach to schedulingof resource persons on National Board for Technical Education (NBTE) accreditation team to a Polytechnic. The level of compliance of the institution to national minimum benchmark for academic standards with respect tostaff mix was deduced.The use of Integer Programming approach and Lingo software in solving the model developed, resulted in considerable drop in accreditation cost from four million, seven hundred and f...
Abstract The frequency of accidental discharge of oil into aquatic environment has presented a significant threat to marine biota with related adverse effects on the supply of products and services of importance to human cultures. This threat of economic and environmental devastation led to the development of a number of monitoring and clean-up alternatives such as remote sensing and chemical dispersants, respective. This study proposed a new possible research direction in marine oil spill mo...
ABSTRACT Replication is the repetition of the treatments under investigation to different experimental unit. Replication is essential for obtaining a valid estimate of the experimental error and to a greater extent, increasing the precision of estimating the pairwise difference among the treatment effects. It is on this note that when full replication (replication of cube and star point) is made, there exists need for optimal replication for the purpose of minimizing biasedness. Some variatio...
ABSTRACT The study aimed at examining the effect of agricultural production on economic growth in Somalia from the period of 1986 to 2016 using time series data. Specifically, the study examined the causality and the effect of agricultural production on GDP growth. The objective was motivated by the fact that the problem statement emphasized that agricultural production has not yielded expected economic growth in Somalia. The study hypothesized that no casualty between agricultural production...
ABSTRACT This study investigated the influence of gross domestic product per capita, total fertility rate and HIV/AIDS prevalence rate (termed as determinants) on maternal mortality of Somalia in the period 1990-2012. This model is dedicated from demographic transition theory-derived from modernization theory. Secondary data between 1990 and 2012 inclusive collected from the publications of United Nations Statistics Division (UNSD) and World Health Organization (WHO) was used for this study. ...
