The currently available yellow fever vaccines are thermally unstable and involve huge costs during preservation and administration. Microencapsulation with thermally stable coating materials is considered as a means of protecting yellow fever vaccines from thermal degradation. Silica nanoparticles have thermal stabilizing abilities but do not possess film forming properties. It is proposed that...

Background: Cold storage facilities required for maintaining vaccine potency are largely inadequate in many low and middle income countries (LMIC). In this study, we have demonstrated the effect of ambient tropical storage conditions on stability and potency of Method: Newcastle disease virus (NDV) vaccine encapsulated in 1,2-dioleoyl-3-trimethyl ammonium propane (DOTAP) cationic liposomes. The...

The assessment of semen quality and reproductive morphometry of two breeds of cocks is based on the evaluation of sperm, the testicular and epididymal morphometry from the breeds of cocks. Two breeds of cocks (Noiler and Rhode Island Red) fed Ficus exasperata leaf meal and vitamin C supplemented diets were evaluated for the semen quality and reproductive morphometry. One hundred and forty-four...

This work investigated the proximate composition, amino acid (AA) and sensory profiles of bread loaves made from blends of wheat, monkey kola and cowpea flours. Monkey kola pulps were extracted from fruit pods and processed into flour. Cowpea seeds were cleaned and separately processed (sprouted, soaked and blanched), dehulled, oven-dried, dry milled and finely sieved into flour. Composite flour...

This paper presents maximum power point tracking improvement using model reference adaptive control (MRAC) scheme. Solar photovoltaic (PV) energy system remains one of the renewable energy applications which operate by tracking energy from the sun and converting it into useful electrical energy. However, harnessing the generated energy has been the major concern of the engineers hence the...
