Development of Clay Foam Ceramic as a Support for Fungi Immobilization to Biodiesel Production (RESEARCH NOTE)

Ultrasound Assisted In Situ Esterification of Rubber Seeds Oil for Biodiesel Production (RESEARCH NOTE)

Since the conventional esterification method requires longer processing time and obtain low yield, the intensification of this process is still interesting subject to be investigated. To reduce the oil extraction cost from seeds which almost 70% of total processing cost, in situ esterification has been recently introduced. The objective of study was to produce biodiesel from rubber seeds oil th...

Immobilization of Streptomyces gulbargensis in Polyurethane Foam: A Promising Technique for L-asparaginase Production on

In the present study, Streptomyces gulbargensis and its mutant form, S.gulbargensis mu24, immobilized on polyurethane foam were investigated for the production of L-asparaginase using groundnut cake extract as medium. The medium with an initial pH of 8.5 was inoculated with free and immobilized cells separately and then subjected to fermentation by incubation at 40oC and shaking at 200 rev/min....

EXPERIMENT AND APPLICATION OF AN ANNULAR FOAM BREAKER FOR FOAM DRILLING FLUID (RESEARCH NOTE)

The annular foam breaker is one which uses the vacuum and shear force generated by the Coanda effect to break foam. Its effectiveness in destroying drilling foam has been test in wellbore flow simulation loop experimental stand. Experimental results showed that the operating pressure of the annular foam breaker should be larger than 0.6MPa and the stabilizers concentration of the foam drilling ...

Influence of Milled Waste Glass to Clay Ceramic Foam Properties Made by Direct Foaming Route

An Algorithm to Compute the Complexity of a Static Production Planning (RESEARCH NOTE)

Complexity is one of the most important issues of any production planning. The increase in complexity of production planning can cause inconsistency between a production plan and an actual outcome. The complexity generally can be divided in two categories, the static complexity and the dynamic complexity, which can be computed using the ant ropy formula. The formula considers the probability of...
