Thank you very much for publishing our manuscript entitled: "Quantification and comparison of bone-specific alkaline phosphatase with two methods in normal and paget's specimens" in the latest issue of the journal (Caspian Journal of Internal Medicine, Summer 2012 3(3):478-483). Unfortunately, we noticed the mistake in the date of our study after its publication in your latest revised manuscrip...

A method to correct for the spatial distortions of gamma cameras has been developed. The method consists of two parts: measuring spatial distortions and repositioning events during accumulation. Distortions are measured using a pattern consisting of parallel slits on 15-mm centers with slit-pattern images obtained in two orthogonal orientations. Slit locations are used to determine X and Y disp...

chemical vapor deposition (cvd) is one of the most important methods for producing carbon nanotubes (cnts). in this research, a numerical model, based on finite volume method, is investigated. the applied method solves the conservation of mass, momentum, energy and species transport equations with aid of ideal gas law. using this model, the growth rate and thickness uniformity of produced cnts,...

A bolometer detector system was developed for the high accuracy infrared spectrophotometer at the National Institute of Standards and Technology to provide maximum sensitivity, spatial uniformity, and linearity of response covering the entire infrared spectral range. The spatial response variation was measured to be within 0.1 %. The linearity of the detector output was measured over three deca...
