Is it permissible for a woman to remove her Hijab in the presence of the paternal uncle of the father and the maternal uncle of the mother?

Greetings to the Scholar Ata Bin Khalil Abu Al-Rashtah from Mamoun Shehadeh, journalist and political analyst I would like to ask you, what were the motivating factors that made Hizb ut Tahrir involve itself in the Syrian revolution and why did it not do so in other places?

If you permit I would like to ask about the one who commits the act of Ribaa (usury) and if he will be in the fires of Hell forever? It relates to the Tafseer of Aayah 275 as found in the book At-Tayseer Fee Usool At-Tafseer. 

There is something that brings about attention and that is the protesters' laid-back attitude towards President Abdullah Gül and the harsh attitude towards Erdogan. The protesters are more satisfied with Abdullah Gül, more than with Erdogan. Does it mean that America has started to advance Abdullah Gül over Erdogan in the administration of the country's affairs, to absorb the indignation of the protesters? And is that expected in the future?
