My wife and I were happily living in a nice duplex in a cool area of Pittsburgh till my job went sour. We then moved to Reading, PA for a better job. I got into a apartment complex that is about 25 older buildings in one complex. They advertised that they provide heat. They have one large boiler in each building and they control the boiler. It runs to the registers to every room in the building, and there is no valve or control on the register.

Computed tomography angiography (also called CT angiography or CTA) is a computed tomography technique used to visualize arterial and venous vessels throughout the body.TA can be used to examine blood vessels in many key areas of the body, including the brain, kidneys, pelvis, and the lungs. Under some circumstances the coronary arteries may be examined by CTA, but CTA has not replaced invasive catheter coronary angiography.
