Simple, economic and sensitive mathematical spectrophotometric methods were developed for the estimation 4-aminoantipyrine in presence of its acidic product.The estimation of binary mixture 4-aminoantipyrine and its acidic product was achieved by first derivative and second derivative spectrophotometric methods by applying here zero-crossing at (va
The periodical cicadas of the genus Magicicada Davis, 1925 inhabiting here eastern United States are characterized by a long juvenile period of 17 or 13 years and periodical mass emergence of adults.In this genus, only seven species are distinguished and are distributed into three species groups, Decim, Cassini and Decula.We performed comparative c
Curcuma longa L., usually referred to as turmeric, is an extensively used spice throughout the world.The curcuminoids (a mixture of three components) present in turmeric, as well as their profile, determine its quality.Consequence quantification and il barone wine profiling of curcuminoids are important.Total quantification and profiling of curcumi
ObjectivePulse transit time (PTT) refers to the time it takes a pulse wave to travel between two arterial sites.PTT can be estimated, amongst others, using the electrocardiogram (ECG) and photoplethysmogram (PPG).Because we observed a sawtooth artifact in the PTT while using standard patient monitoring equipment for ECG and PPG, we explored the rea
Melioidosis is a frequently fatal infectious disease caused by the soil dwelling Gram-negative bacterium Burkholderia pseudomallei.Environmental sampling is important to identify geographical distribution of the organism and related risk of infection to humans and livestock.The aim of this study was to evaluate spatial distribution of B.pseudomalle
