Crude oil pollution reduces soil fertility, suppresses beneficial microbial activity, and limits crop productivity in oil-producing agricultural areas. This study evaluated the capacity of Vetiveria zizanioides and Panicum maximum, used si…
View publication →This study investigates the sensitivity of European call option prices to volatility under the Black-Scholes framework for deep in-the-money contracts. Using the stock quantity parameter values to compute, the results show a monotonic and …
View publication →We model daily price dynamics of BUA Cement and BZU Cement on the Nigerian Group Exchange (NGX) as three-state Continuous-Time Markov Chains (CTMCs) representing Low, Mid, and High regimes. Using nine months of data, estimated generator ma…
View publication →Hypertension remains one of the leading causes of cardiovascular morbidity and mortality worldwide, with increasing prevalence in low- and middle-income countries, including Nigeria. Nurses play a pivotal role in hypertension prevention th…
View publication →This study presents a nonlinear mathematical model for investigating the impact of antimalarial drug intervention on the transmission dynamics of malaria in a coupled human–mosquito population. The total population is divided into suscepti…
View publication →Antepartum haemorrhage (APH) remains a leading cause of maternal and perinatal morbidity and mortality, particularly in low- and middle-income countries where delayed recognition and inadequate preventive practices contribute substantially…
View publication →Technology transfer is a fundamental mechanism for enhancing indigenous technological capability, promoting industrial development, and reducing dependence on foreign expertise within the petroleum sector. Despite Nigeria's comprehensive l…
View publication →Blockchain technology has emerged as a foundational infrastructure for decentralized financial systems and secure digital transactions; however, its resilience against evolving cyber threats remains a significant challenge. This study pres…
View publication →Access to safe, affordable, and sustainable domestic water remains one of the major public health and development challenges confronting Nigeria despite the country’s extensive surface and groundwater resources. Rapid population grow…
View publication →Sickle cell disease (SCD) remains one of the most important inherited blood disorders and ncontinues to constitute a major public health challenge in Nigeria, which bears the highest global burden of affected births. Despite improveme…
View publication →The use of cryptographic algorithms in providing privacy and integrity of data to central bank digital currencies have been considered to be the most important infrastructure to be deployed by any nation as a requirement for safe…
View publication →Trachoma remains one of the leading infectious causes of preventable blindness in many developing regions, where environmental conditions, poor sanitation, and limited access to healthcare contribute significantly to disease persistence. T…
View publication →This paper investigates the distribution of symmetric prime pairs around the midpoint of even integers. For a given even integer $2n$, prime pairs $(p_1,p_2)$ symmetrically positioned about $n$ are considered, satisfying $$ n-p_1 = p_2…
View publication →This paper develops a comprehensive categorical and spectral framework for the analysis of evolving X-top lattices. An X-top lattice is modeled as a bounded distributive lattice endowed with an interior-type operator, while an evolving X-t…
View publication →The study of symmetry remains one of the most important themes in modern mathematical physics, providing a rigorous framework for understanding conservation laws, quantum state transitions, and dynamical invariants. Finite groups offer nat…
View publication →The choice of algebraic structure is a central problem in modern cryptography, especially in the transition from classical public-key schemes to quantum-resistant security models. Classical cryptographic systems such as RSA and elliptic cu…
View publication →The migration from classical public-key cryptography to post-quantum cryptography requires systematic methods for identifying algebraic structures whose computational properties remain secure against both classical and quantum adversaries.…
View publication →Typhoid fever is a highly infectious disease, and remains a major public health problem, especially in low- and middle-income countries, despite several interventions such as environmental sanitation, personal hygiene, vaccination, and tre…
