LIPIDS COMPOSITION IN THE EGG SHELL OF DOMESTIC FOWL

ABSTRACTPoultry eggs are eaten in most areas of the world with fewer social taboos associated with them than pigs and cattle. The most commonly used bird eggs are those from chicken. In Nigeria, the domestic foul dominates the poultry industry. Of the 120 million indigenous poultry population in Nigeria, the domestic fowl constitutes about 91 % of this. For this reason, the present work tried to evaluate the nutritional levels of the lipid composition of the free-range fertilize...

SYNTHESIS AND CHARACTERIZATION OF PYRIDYL BASED SCHIFF

Metal complexes are scientifically known to be active and effective as antibacterial, antivirus and some antifungal etc. This project work is targeted at preparing complex from transition metals say; cobalt, cupper, zinc and nickel and organic ligands synthesised from pyridyl based schiff bases, one from 2-aminopyridine and benzaldehyde and second from 2-aminopyridine and 2,4-dihydroxylbenzaldehyde. The analysis and completion is based on thin-layer chromatography, column-chromatography and I...

ISOLATION AND CHARACTERIZATION OF LUPEOL FROM THE METHANOL LEAF EXTRACT OF TAPINANTHUS DODONEIFOLIUS GROWING ON VITEX DONIANA

Tapinanthus dodoneifolius belongs to the family Loranthaceae and is widely distributed in West Africa, Europe and Asia, commonly known as mistletoe. It exhibits a wide array of pharmacological activities including antimalarial, anticonvulsant, anti- microbial, and is effective in the relief of menstrual and stomach pain. Lupeol, a pentacyclic triterpenoid was isolated for the first time from the methanol leaf extract of Tapinanthus dodoneifolius and characterized by spectral analysis. The...

Adsorption efficiency of coconut husk for removal of Rhodamine-B dye from aqueous solution

ABSTRACTThe efficiency of acid modified locust bean pod (ALBP) as low cost adsorbent to remove Rhodamine-B (Rh-B) dye from aqueous solution was studied. The morphology, functional groups and elemental analysis of the adsorbent were investigated by SEM, FTIR, pH (pzc), and Boehm titration analyticaltechniques. Operational parameters such as contact time, initial dye concentration and solution temperature were investigated. The amount of Rh-B dye adsorbed was found to increase as these opera...

Corrosion Inhibition of 5-Methyl-2H-imidazol-4-carboxaldehyde and 1H-Indole-3-carboxyaldehyde on Mild Steel in 1.0 M HCl: Gravimetric Method and DFT Study

AbstractWeight loss and Density Functional Theory (DFT) methods were used to study the corrosion inhibition of 5-methyl-2H-imidazol-4-carboxaldehyde and 1H-Indole-3-carboxaldehyde on mild steel in acid medium. The values of thermodynamic parameters such as free energy of adsorption (ΔGºads), adsorption equilibrium constant (Kads), adsorption entropy (ΔSºads), adsorption enthalpy (ΔHºads) and activation energy (Ea) were calculated and discussed. The adsorption process on mild steel surfa...
