The given work presents the methodology of R-peaks detection in an electrocardiogram signal based on Discrete Wavelet Transformation. The optimal level decomposition of the detail coefficients can be determined by energy, frequency and cross-correlation a... see more

Electrocardiography (ECG) is a non-invasive technique that is used to diagnose heartabnormalities. ECG records all heart activities and represent them using bio electricsignals. Arrhythmia is one of the cardiac disorder that can be detected using ECG.Arrh... see more

A new ultraviolet derivative spectrophotometry (UVDS) method has been developed for determination of reserpine in antihypertension tablets. A first-order UVDS based on the measurement of the distance between peaks to baseline (DZ) at the wavelength of 312... see more

Crude glycerol is a major by-product of biodiesel production and is an economical additive feed for ruminants. However, residual methanol in crude glycerol can be harmful to animal health. Several methods exist for quantifying methanol residues in biodies... see more

An HPLC method was developed for the quantification of biogenic amines in insect hemolymph. The major challenge in the analysis is that a typical sample only contains a few hundred pictograms of the amine. A C18 column and electrochemical detection was us... see more

A simple, sensitive reproducible and cost effective reversed-phase liquid chromatography (RPHPLC) method coupled with a photodiode array detector was developed and validated for determination of Flucytosine and its related substances in pharmaceutical dos... see more

A one-step real-time RT-PCR assay (RT-qPCR) with melting curve analysis, using the green fluorescence dye SYBR Green I, was developed to detect and quantify RNA targets from Apple mosaic virus (ApMV), Apple stem grooving virus (ASGV), Apple stem pitting v... see more

We studied the subset of optical light curves of gamma-ray bursts with measured redshifts and well-sampled R band data that have clearly detected peaks. Among 43 such events, 11 are promptoptical peaks (P), coincident with gamma-ray activity, 22 are purel... see more

A simple, rapid, and sensitive reversed-phase HPLC method was developed and validated for determination of paclitaxel (PTX) in plasma, various organs and tumor tissues of tumor-bearing mice. Tissue specimens of liver, kidneys, spleen, lungs, heart and tum... see more
