Mixing aqueous solutions of sodium diclofenac (DIC-Na) and ranitidine hydrochloride (RAN·HCl) afforded an off-white solid (DIC-RAN) that was investigated from the microscopic, thermal, diffractometric, spectroscopic, and functional (chemometrics-assisted dissolution) points of view. The solid has a 2:1 (DIC:RAN) molar ratio according to (1)H nuclear magnetic resonance spectroscopy. It is therma...

Sir, Nowadays methods of X-ray diagnostics together with medical drugs or devices with contrasting properties may be used for imaging of humans and animals body parts. Intravascular and intracavitary injection of the X-ray contrast agent solutions is a common practice in clinical settings. However, it is known that the use of radiological methods of X-ray diagnostics together with contrast agen...

Non-destructive testing (NDT) by active infrared thermography requires of data processing techniques in order to: i. improve the thermal contrast between defective and non-defective areas, and ii. reduce the large quantity of images recorded during the inspection without losing relevant information. In this paper, the use of the skewness statistic parameter is proposed for the automatic process...

BACKGROUND Accuracy in feature extraction is an important factor in image classification and retrieval. In this paper, a breast tissue density classification and image retrieval model is introduced for breast cancer detection based on thermographic images. The new method of thermographic image analysis for automated detection of high tumor risk areas, based on two-directional two-dimensional pr...

Thermogravimetric analysis of polyethylene oxide (powder and nanofibers obtained by force spinning water or chloroform solutions oxide) was studied using different theoretical models such as Friedman Flynn-Wall-Ozawa. A semiempirical approach for estimating the “sigmoid activation energy” from thermal degradation suggested confirmed experimental data on PEO powder nanofibers' mats. The equation...
