Sawdust is a by-product of woodwork operations such as sawing, sanding, milling, planning and routing. It mainly composed fine chippings wood. This study compares contrast the properties carbonized non-carbonized briquettes made from sawdust. Eight (8) different samples were synthesized (four (4) for non–carbonized four briquettes) with equal binder concentrations 3.0, 5.0, 7.0 9.0 % w/w respec...

Iris mammillations are dark brown, smooth, mound- or dome-shaped protuberances that are typically found on the anterior iris surface and are presumed to be congenital in origin. This congenital anomaly is usually unilateral and can be hereditary or sporadic. Lisch nodules in neurofibromatosis, tapioca melanoma of the iris, inflammatory iris granulomata and Cogan-Reese syndrome should be conside...

Changes in the physicochemical properties of wheat, sago, tapioca and potato starches were studied after heating for 1 hour at 100oC, 110oC, and 120oC and for 2 hours at 120oC. These properties were characterised through the swelling behaviour of starch granules, amount of carbohydrate materials leached from the granules, starch paste retrogradation rate and gel strength. For all starches excep...

In order to achieve satisfactory biological treatment of wastewater, the wastewater should contain sufficient carbon, nitrogen, phosphorus, and trace minerals to meet the metabolic requirements for cell growth. For most food processing wastes, nutritional balance is not a problem since there usually is enough carbon, nitrogen, phosphorus, and trace minerals. However, certain food processing was...

The objective of this research was to study the effect of water activity and glass transition temperature on the fat hydrolysis in a food model system. The model system was prepared with tapioca starch, casein, palm oil and sugar as 58, 14, 16 and 12 g/100 g model matrix, respectively. Hydrolysis reaction was accelerated by commercial lipase at six levels of water content and water activity. Mo...

Kinetic study for different start up conditions of the anaerobic digestion of wastewater derived from the sago processing from tubers of tapioca (Mannihot utillisema) is discussed. The experiment is carried out with synthetic waste water using a tapered fluidized bed reactor. Mesoporous granulated activated carbon is used as a bacterial support. The kinetic model follows half order kinetics for...
