Biomass-plastic Co-pyrolysis for sustainable biochar: Mechanisms, reactor technologies, and circular-carbon applications

The rapid accumulation of lignocellulosic biomass residues and plastic waste poses significant environmental challenges because conventional disposal methods, including landfilling and incineration, contribute to greenhouse gas emissions and inefficient resource use. Biochar prod...

Forecasting Product Demand and PET Bottle Return Flows in Closed Loop Supply Chains: A Hybrid Machine Learning Approach for Emerging Markets

This study examined whether monthly demand and PET bottle return forecasts improve planning in a closed-loop beverage network in Nigeria. The analysis covers Coke, Fanta, Sprite, Big Cola, and Eva from 2019 to 2024, combining product observations with variables calibrated from th...

Integrated Household Environmental Health Conditions and Their Independent Predictors in an Urban Nigerian Community: A Community-Based Cross-Sectional Study

Household water, sanitation, waste management, food hygiene and housing conditions interact to shape environmental health risks. This study assessed these domains together and identified independent predictors in an urban Nigerian community. A community-based cross-sectional surv...

Evaluation of serum and salivary interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF- α) biomarkers in patients with temporomandibular disorders

Biomarkers like TNF-α and IL-1 are increasingly recognised as promising tools for enhancing TMD diagnosis and treatment. These biomarkers are detectable in synovial fluid, saliva, and blood. Salivary and serum biomarkers are increasingly favoured over synovial fluid biomarkers be...

Impact of Restorative Treatment for Intrinsic Tooth Discoloration on Oral Health-Related Quality of Life: A Prospective Longitudinal Study

Abstract Background: Intrinsic tooth discoloration can adversely affect oral health-related quality of life (OHRQoL), particularly through its esthetic and psychosocial consequences. However, evidence on changes in OHRQoL following restorative treatment remains limited, particula...

Quadratic Relationship Between Tool Angle of Lift and Draught in an Inclined Narrow Model Chisel Blade: A Soil Bin Parametric Study and Empirical Model Development

Tool geometry is an underused lever for trimming tillage energy, yet the lift angle that minimizes draught for inclined narrow tools in tropical loamy sand has rarely been quantified. This study established the relationship between the tool angle of lift (β) and draught for an in...

Addressing infertility as an overlooked priority in the reproductive health agenda in Africa

Infertility is one of the great paradoxes of reproductive health in Africa. The continent has some of the world's highest fertility rate1, yet it also carries a disproportionately high burden of infertility2. Despite this, infertility remains one of the least prioritised componen...

Challenges of Perioperative Management and Outcome of Neonates with Gastroschisis in a Tertiary Hospital in Southern Nigeria

Gastroschisis is a congenital full thickness anterior abdominal wall defect with exposure of intraabdominal content of varying degree and affected neonates are at risk of fluid loss, sepsis, hypothermia, and metabolic derangements. Perioperative management plays a pivotal role in...

Waste-To-Energy Conversion for Sustainable Electricity Generation in Lagos, Nigeria: A Thermodynamic and Environmental Analysis

Rapid urbanization and increasing municipal solid waste generation in Lagos, Nigeria, have intensified environmental challenges and energy deficits. This study investigates the potential of waste-to-energy (WtE) conversion as a sustainable pathway for electricity generation, usin...

Mechanical and durability properties of concrete mixed and cured in hypersaline water

Abstract This study investigates the influence of hypersaline water on the compressive strength, bleeding, and water absorption of concrete, comparing freshwater and saltwater curing environments. Mixes were prepared using 0%, 10%, 15%, 20%, and 30% saltwater by weight of mixing...

Ethical Standards Compliance and Healthcare Services Delivery in Edo State Public Hospitals

Healthcare service delivery is described as the cornerstone of public trust in government. This study examined the influence of ethical standards compliance on healthcare service delivery in Edo State public hospitals. Specifically, it assessed the current state of ethical compli...

RELIGIOUS FESTIVALS, RITUALS, AND PHYSICAL MOVEMENT: A HUMAN KINETICS PERSPECTIVE

This article examines the intersection of religious festivals, rituals, and physical movement through the lens of human kinetics. Drawing on interdisciplinary research from anthropology, religious studies, and sport science, the article explores how bodily movement functions as a...

Emergency obstetric referrals in public primary health care centres in Benin City, Nigeria: a qualitative study

The aim of this study was to assess the mechanisms, procedures, and processes of the referral system for emergency obstetric care (EmOC) in public primary health care centres (PHCs) in Benin City, Edo State, Nigeria, with recommendations offered to address the challenges. A quali...

Analysis and Implementation of Minimum-Redundancy Huffman Codes

This student research project analyzes David A. Huffman's 1952 paper, "A Method for the Construction of Minimum-Redundancy Codes." The document explains the theory of minimum-redundancy prefix-free codes, formulates the greedy merging property behind Huffman coding, and designs b...
