减速带

Multi tool use
减速带(部分地区也称为减速器、减速带,臺灣稱减速丘[1])是一种平行设置于公路路面上,略微由地面向上凸起约10-15厘米的装置。其目的是为了强制使行过的车辆减速。减速带通常由再生橡胶、金属、塑料或是沥青等材料制成。
减速带在世界范围内被广泛的使用,并通常设置在应低速度行驶(小于每小时40公里)的路段以及停车场内(每小时8-16公里)。尽管使用减速带能够有效的降低行车速度,但因车辆通过其时所产生的噪音,以及高速通过时可能对车辆造成损害,使得使用减速带在一些地区也成为了一项争议。

This is an entry in the Fortnightly Topic Challenge #41: Short and Sweet. 1 letter only could be mean anything . With an additional letter in front , could be used as medicine component and something you definitely learn or at least heard once. Add another letter in front , you would possibly hear that many times . Add an additional letter in front , you would found an independent country . With an additional letter, in the end , you would found something related to apple . Add another letter in the end , you would found something bad . Hint: Each letter is unique .

I am trying to run a scheduled task with User Group (not a single user). This is working fine when I in the field "when running a task, use the following user account:" insert BUILTIN User Group (for example: Administrators or Users). But when I try it with the created Local User Group (example: TestGroup) it is not working. The Users in the TestGroup are the same as in the Administrators group. What could be the problem? Are there some restrictions to the Created User Group compared to BUILTINUsers?
