Characterization of healthcare waste in Tanzanian zonal referral hospitals as a key factor for energy recovery

In this study, healthcare waste (HCW) generated in four referral hospitals in Tanzania namely: Muhimbili National Hospital (MNH), Kilimanjaro Christian Medical Center (KCMC), Bugando Medical Center (BMC) and Tumbi Regional Referral Hospital (TRRH) was characterized to establish its feasibility for energy recovery. The HCW collected and loaded into the incinerators was weighed and its composition determined (as highly...

Physicochemical and metal quality evaluation of the ground water of the chief town of Sinthiou Maléme Commune in Tambacounda (Senegal)

In underdeveloped countries, particularly, medium rural areas, the subsoil waters constitute an invaluable resource. However, they remain fragile and vulnerable because of demographic pressure, uncontrolled exploitation of discharges, and absence of adequate cleansing system and husbandries. This present work aims to evaluate the physicochemical and metal quality waters of 10 wells collecting the ground water of...

Evaluating the rate of total electron content (TEC) production in ionosphere F2-layer to highlight winter anomaly by running thermosphere-Ionosphere-electrodynamics general circulation model

The study deals with determining ionosphere parameter at low latitudes during the maximum of solar cycle 22 on quiet days. It uses Thermosphere-Ionosphere-Electrodynamics General Circulation Model (TIEGCM) to carry out Total Electron Content (TEC) parameter in the ionosphere region. TEC time variability on summer and winter highlights a seasonal anomaly, a phenomenon observed since 1965 and which appears while...

Biodegradation of hydrocarbon by Enterobacter sp IAA-01 isolated from hydrocarbon exploration site soil of Kukawa Northeastern Nigeria

The accidental release of diesel and other hydrocarbon to the environment lead to the pollution of the environment. The search for an environmentally friendly technique for the remediation of such polluted environment is not to be overemphasis. Microorganisms are used in the bioremediation of polluted environments. Hydrocarbon-degrading bacterium isolated from the hydrocarbon exploration site soil of Kukawa...
