Q: Review: There are plenty of tension rods out there. The _only_ advantage of the Umbra rods is that they look better. (Why other manufacturers haven't figured out the design part is anybody's guess.) The problem with the Umbra rods -- all of them -- is NO tension. I have tried these repeatedly.... Why? Because my local hardware store carries them, and they are readily available elsewhere, and I have opted for form over function. Every single Umbra rod I have used fails drastically. They simply cannot bear any weight. Or, to put it differently, they cannot exert enough force against the surfaces they extend out to for them to bear any load. Worse, the springs that are the key element in sustaining the tension tend to fail. When those springs fail, anything you have suspended by the rod will come down. If it's a lightweight drapery panel, you may be in luck. Otherwise, forget about it.

Q: Review: So they release a DVD to say how good "Back in Black" is (as if we needed to be remembered of that...) and they put a photo at the front cover with SIMON WRIGHT in the line-up, instead of Phil Rudd! Wright joined the band THREE YEARS after the recording of "Back in Black".This fact alone is a very good omen of the real intentions of this product: to make easy and fast money and offering nothing new about this classic rock album. Useless.

Q: Review: An excellent scholarly book. Great detail and very in depth analysis. Inevitable conclusion is the impossibility of molding an economic system out of a moral philosophy, not just Islam. That is where the problem with traditional Islamic thought arises, for most of its adherents, Islam is not just a set of moral principles but a way of life, dictating every aspect of it. Unavoidably, there was much effort by Islamists to set up a distinct system of banking and economy based on pure Islamic traditions. Prof. Kuran delves into the history of these movements, but he does more than that, he puts all this in cultural and political context. At the end, he bravely expands more on the general failure of Islamic culture and tradition to bring wealth and prosperity to the masses that follow it. Writing is very formal, not the easiest read and surley apporpriate only for the truly intersted in the general topic, but it was well worth it for this reader.
