OBJECTIVES The goal of this study was to validate the prognostic value of the drop in heart rate (HR) after exercise, compare it to other test responses, evaluate its diagnostic value and clarify some of the methodologic issues surrounding its use. BACKGROUND Studies have highlighted the value of a new prognostic feature of the treadmill test-rate of recovery of HR after exercise. These studi...

A sensitive fluorometric method for the determination of deferiprone (DFP) based on the formation of a luminescent complex with Tb3+ ions in aqueous solutions is reported. The maximum excitation and emission wavelengths were 295 and 545 nm, respectively. The effects of various factors on the luminescence intensity of the system were investigated and optimized, then under the optimum conditions,...

The manufacturing equipment in pharmaceutical industry, could be used in multiple and sharedproduction lines, therefore there is the possibility for the products components and active ingredients tointermix and pollute one another. In this purpose the cleaning methods are used, to reduce the residueslevels from the machinery surfaces and decrease the residues to acceptable level but these metho...

Compressive sensing (CS) is a data acquisition technique that measures sparse or compressible signals at a sampling rate lower than their Nyquist rate. Results show that sparse signals can be reconstructed using greedy algorithms, often requiring prior knowledge such as the signal sparsity or the noise level. As a substitute to prior knowledge, cross validation (CV), a statistical method that e...
