Its not temporal, its temporary. I accidentally used the spanish word instead of the english word, what also happens to have a totally unrelated meaning for english readers.
Temporary consequences are something that makes thing harder for the character for a while, but are gone as soon as you can take some time to remove/heal/fix them (Think in a dislocated shoulder), while persistent consequences are going to stick for a while (Think in a broken arm). And yes, you may use the D10 to determine if you get one, but you can use a coin too if you wish.
A complication means that you had success in whatever you were trying to do, but you also likely created a new problem while doing so: Imagine the player triying to repair a machine. He get a sucess with a complication, meaning that he fix the system by bypassing a burnt fuse. However, while this will work for the short term, the true problem will remain unsolved, and later the machine will starts malfunctioning in an unpredicatable way.
