EDITOR'S NOTES

ASEAN Journal of Chemical Engineering, volume 5 number 2, features eight papers presented during RSCE 2003 and 2004. Of these papers, four came from Malaysia, two each from the Philippines and Indonesia, and one from Thailand, with coauthors coming from Australia, Austria, and the U.K. From these paper, find out how

M. Nasikin and A. Wahid (Malaysia) explore how ultrasonic irradiation increased catalyst activity to convert CO2 to methanol as an alternative technology;

S. Muryanto (Indonesia) and H.M. Ang (Australia) evaluate a laboratory project on the formation of calcium sulfate dihydrate scales on various types of pipe surfaces under various isothermal conditions;

A. W. Lee, N.M. Ghasem, and M. A. Hussain (Malaysia) review mathematical program languages and how each one can be applied to specific chemical engineering problem;

C.M. Ling, A.R.Mohamed, and S. Bhatia (Malaysia) study the photocatalytic degradation of methylene blue and phenol to come up with data useful for the design of a photocatalytic reactor for the treatment of organic pollutants in waste streams;

R.G.R. Tan (the Philippines) elucicates fuzzy SAW algorithm as the preferred approach in assessing different technological options involving multiple criteria and data uncertainty, which is possibilistic rather than probabilistic, to arrive at optimal integrated waste management and process plant retrofit;

J. Wittayakun, N. Grisdanurak, B. Nuntaitawegon (Thailand), G. Kinger, and H.Vinek (Austria) come up with the optimum conditions for the catalytic reduction of nitric oxide by CO over cobalt using Co/BEA catalyst;

A. N. Soriano and B.T. Doma, Jr. (the Philippines) lay down the bases why ionic liquids, a new class of solvents, are potenitally the most viable alternative to VOCs which are major contributors to air pollutions;

C. R. Che Hassan (Malaysia), M.J.Pitt, and A.J. Wilday (the United Kingdom) identify the strengths and weaknesses of performance indicators in the audit of process safety management system;

Sumardi P., I.B. Agra, I.M. Bendiyasa, and Wahyudi B.S. (Indonesia) uncover the burning ability of concrete demolition rubble to establish these waste products as alternative to limestone as corrective materials in Portland cement production;

A. Trianto, Y.Bindar, and Noezran (Indonesia) evaluate the performance of an MPMR in simultaneuously producing propylene of both chemical and polymer grades, specificially to remedy the absence of a propane-propylene splitter and to replace traditional cracking methods.

We inform our readers that (a) continuous pagination will be used starting with this issue to facilitate indexing, and (b) that we have a shorter URL, http://ajche.dlsu.edu.ph/ that will be easier to remember. Also, we acknowledge the valuable comments and suggestions from our evaluators who, despite their busy schedules, shared their insight and expertise with us.
This only goes to show that research and publication need collective effort in order to thrive and succeed.
