Paperbricks produced from wastes: modeling and optimization of compressive strength by response surface approach.

The high cost of building materials occasioned by the increased cost of constituent materials has contributed immensely to the problem of housing deficit faced in Africa and major developing countries of the world. Waste paper can be recycled into bricks but there are limited studies to that effect. Waste glass is used as partial cement replacement to reduce the cost of cement and is also used as a pozzolan.

Mathematical modelling, multi-objective optimization, and compliance reliability of paper-derived eco-composites.

The quest for cost-effective and thermal efficient structural materials onto beating the high cost of construction is gaining more attention among researchers. This study focused on the blending of cement and sand with waste paper pulp into cost-effective structural materials. The composites were prepared in four mix groups with each containing a fixed amount of sand at 5, 10, 15, and 20 wt.

Update on first African clinical trial on earpopper for the treatment of otitis media with effusion [FCT/UATH/HREC/PR/330].

Background: Otitis media with effusion (OME) is a middle ear condition characterized by the accumulation of serous fluid. It is common, though not exclusive; among children with its attendant developmental consequence if missed or untreated in early life. OME could be managed surgically, pharmacologically, or physiologically.

Sensorineural Hearing Loss among Hypertensives.

Background: The effect of hypertension on the vascular system leads to Target Organ Damage (TOD). The cochlea is one of the target organs affected by hypertension, giving rise to Sensorineural Hearing Loss (SNHL).

Objective: To determine the prevalence and pattern of Sensorineural Hearing Loss (SNHL) among hypertensives.

Age-related hearing loss at Gwagwalada area council of federal capital territory, Abuja.

Background: Presbyacusis is a cause of hearing loss in adults worldwide. It is a type of auditory dysfunction thought to be due to a series of insults over time including agerelated degeneration, noise exposure, and diseases of the ear. It usually affects the high frequencies of hearing.
