立方晶系

Multi tool use
立方晶系,也叫等轴晶系,它有4个三重对称轴以及3个互相垂直的4次对称轴或者3个相互垂直的二重对称轴。其中的3个互相垂直的4次对称轴或者3个相互垂直的二重对称轴是晶体结晶轴。轴角α=β=γ=90o,轴单位a=b=c。所以凡是等轴晶系的晶体在各个方向上的性质——光学性质、电磁性、折射率都相同。即具有所谓各向同性。

I have 4 tables namely stud, country_master_academic,master_state and master_city. The main problem is that my form consists of many different fields like textbox, radio buttons, dropdown and an image file, so i am getting really confused. I can't insert data in database. Please help me. I tried many times but its not working. Thanks for the help in advance.

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?
