THE DESIGN AND ANALYSIS OF EXPERIMENTS. By Oscar Kempthorne. New York, John Wiley and Sons, Inc., 1952. 631 pp. $8.50. This book by a teacher of statistics (as well as a consultant for \"experimenters\") is a comprehensive study of the philosophical background for the statistical design of experiment. It is necessary to have some facility with algebraic notation and manipulation to be able to use the volume intelligently. The problems are presented from the theoretical point of view, without such practical examples as would be helpful for those not acquainted with mathematics. The mathematical justification for the techniques is given. As a somewhat advanced treatment of the design and analysis of experiments, this volume will be interesting and helpful for many who approach statistics theoretically as well as practically. With emphasis on the \"why,\" and with description given broadly, the author relates the subject matter to the general theory of statistics and to the general problem of experimental inference.

Weathered crude oil (WCO) removals in shoreline sediment samples were monitored for 60 days in bioremediation experimentation. Experimental modeling was carried out using statistical design of experiments. At optimum conditions maximum of 83.13, 78.06 and 69.92% WCO removals were observed for 2, 16 and 30 g/kg initial oil concentrations, respectively. Significant variations in the crude oil degradation pattern were observed with respect to oil, nutrient and microorganism contents. Crude oil bioremediation were successfully described by a first-order kinetic model. The study indicated that the rate of hydrocarbon biodegradation increased with decrease of crude oil concentrations.

Ex-situ Bioremediation of Crude Oil in Soil, a Comparative Kinetic Analysis

Leachate generated from one of the old landfills in Malaysia contains high concentrations of colour, COD, iron and ammoniacal. The ability of activated carbon-zeolite mixtures as an adsorbent was investigated in this research. Results of the batch experiments indicated that more than 522.2 mg/g of colour, 52.63 mg/g of iron, 232.6 mg/g of COD and 21.01 mg/g of ammoniacal nitrogen were removed by a mixture of activated carbon and zeolite. Results of the column studies indicated that more than 70% of colour and ammoniacal nitrogen, 80% of COD and 90% of iron were removed on the first five days.
