Measuring the effects of salinity stress in the red mangrove, Rhizophora mangle L.

The mangrove habitat exhibits many unique physical features, one of the most important of which is a salinity gradient. Photosynthetic rates, as measured by leaf stomatal conductance and leaf chlorophyll fluorescence induction, were tested as indicators of salinity stress in seedlings of the red mangrove, Rhizophora mangle, grown under five different salinity levels: 0, 15, 30, 45, and 60 parts per thousand....

Scientific research in Africa in the 21st century, in need of a change of approach

The scientific research environments in industrialized and non-industrialized countries are compared, mainly as far as supportive industries and services to agricultural producers are concerned. Further environmental deterioration and alienating poverty are often a consequence of the observed absence of focused assistance. It is then discussed why and how Africa should change its scientific research and develop its own...

Effect of local preservative (Aframomum danielli) on the chemical and sensory properties of stored warakanshi

The effect of local preservative (Aframomum danielli) on the chemical and sensory properties of stored warakanshi was investigated. Fresh milk was processed traditionally into warakanshi and Aframomum danielli was added at 1, 2 and 3%, stored at 27±20C, 7±20C and evaluated at 0, 3 and 6 days for moisture, pH, protein, ash, peroxide value and sensory properties. Drop in pH was more prevalent at...

Evaluation of some quality attributes of soybean oils in Ibadan

Soybean oil is popularly used for the processing of margarine, shortenings and soaps, but there is limited information about some quality attributes of the oil. soybean oil was processed from four popular varieties and evaluated for chemical indexes (saponification, Acid, peroxide and iodine values) and sensory characteristics by untrained male and female adults TGX 1440-1E had the lowest saponification value of (96.78...
