This study aimed to translate the 31-item Quality of Life in Epilepsy Inventory (QOLIE-31) into Vietnamese and validate the translation. Methods: The inventory was translated through “forward – backward” translation, and culturally adapted for standardization. To ensure the reliability of the inventory, the internal consistency and the temporal consistency was determined. Clinical variables were tested for discriminant validity by comparing their scores.

These test methods of chill testing apply to gray irons that are to be free of chill in the casting and to chilled irons that are to have a specific depth of chill in the casting. Two test methods of determining the chilling tendencies of cast iron are covered as follows. For many applications either test method will be satisfactory if test pieces of the proper dimensions are selected.
