This paper presents an experimental study that helps to determine the optimum exchanged diameter in surface grinding. In the paper, the cost of a surface grinding process was analysed. In the cost structure, the effects of the cost parameters such as machine tool hourly rate, grinding wheel cost were taken into account. Also, process parameters including the initial grinding wheel diameter, the wheel life, the dressing regime and so on were investigated. Based on the cost structure, the set up and the procedure of the experiment for finding the optimum diameter was pointed out. From experimental results, the optimum exchanged grinding wheel diameter was found. Grinding with the optimum exchanged diameter, both the grinding cost and grinding time can be reduced significantly.

To evaluate the accumulation of oil and fatty acids in coriander during fruit ripening, a field experiment was conducted under organic cultivation conditions in Auch(near Toulouse,southwestern France) during the 2009 cropping season. The percentage and composition of the fatty acids of coriander were determined by gas chromatography. Our results showed that rapid oil accumulation started in early stages(two days after flowering, DAF). Twelve fatty acids were identified. Saturated and polyunsaturated acids were the dominant fatty acids at earlier stages(2–12 DAF), but decreased after this date. After this stage,petroselinic acid increased to its highest amount at 18 DAF. In contrast, palmitic acid followed the opposite trend. Saturated and polyunsaturated fatty acids decreased markedly and monounsaturated fatty acids increased during fruit maturation. It appears that the fruit of coriander may be harvested before full maturity.
