|BEAMnrc was used to derive the X-ray spectra, from which HVL and homogeneity coefficient were determined, for different kVp and filtration settings. Except for the peak at 61keV, the spectra are in good agreement with the IPEM report 78 data for the case of filtered beams, whereas the unfiltered beams exhibit softer spectra. Although the current attenuation data deviates from the IPEM 78 data by ∼±0.5%, this has negligible effects on the calculated HVL values.

The World's Longest Tram Got A Bit Shorter After This Crash
Siemens delivered 40 Combino Plus trams to Budapest back in 2007. These happen to be the world's longest passenger trams at 177.13 feet, although one is a little shorter now thanks to this accident. The 'giant caterpillar' is down, and here's what happened. »

text: This is the story, I purchased my 03 Pista new in Feb. 03. I added bull horns and a brake and I rode the bike exclusivley for a year. My riding consisted of commuting and sunday club rides. The following spring the b.b got noisey so i had my lbs replace it, within a month the cup backed out of the frame locking the cranks. I replaced the b.b.a second time, and it's noisey again. In addition the head set feels notchy and the front hub is so worn that the bike tends to wander. I swaped the front wheel with a spare roadie wheel (Mavic Hellium) and it tracks straight. My question is do i uprade this bike? or fix it and sell it? I've read that this frame is poor quality, as are the components. I'm ready to have a quality set of wheels built, replace the bb and cranks (to get rid of the truvativ set up) and install a new headset. I love the way it rides, but i have never experienced another fixed gear bike. Any input would be great!
