The quaternion Fourier transform (QFT), which is a nontrivial generalization of the real and complex Fourier transform (FT) using quaternion algebra has been of interest to researchers for some years (see e.g. [3, 5]). It was found that many FT properties still hold but others have to be modified. Based on the (right-sided) QFT, one can extend the classical wavelet transform (WT) to quaternion ...

Infrared rheo-optics combines dynamic mechanical analysis with infrared spectroscopy to provide molecular level information about the segmental reorientation and the changes in local environment associated with the dynamic deformation of polymers. Up to now, the application of this technique has been limited by the amount of time necessary to perform the experiments. In this article, we demonst...

In this paper, the focus is on a new kind of biodegradable semi-interpenetrating polymer networks, which derived from ɛ-caprolactone, lactide, 1,4-butane diisocyanate and ethylenediamine and also its potential has been investigated in soft tissue engineering applications. The polymers were characterized by nuclear magnetic resonance (NMR) spectrometry, fourier transform infrared spectroscopy (F...

The Anti-angiogenic Activity of Phoenix dactylifera seeds methanol extract in vivo study Abstract: The aim of the study was to identify the antiangiogenic activity of Phoenix dactylifera seeds methanolic extract in vivo and the probable anti-angiogenic mechanism of action. The date seeds were extracted with methanol using cold method, the crude extract was tested on chick chorioallantoic ...

Weyl points are point degeneracies that occur in momentum space of periodic materials, and associated with a quantized topological charge. We experimentally observe 3D micro-printed photonic crystal charge-2 can be split into two charge-1 as the protecting symmetry original is broken. Moreover, we use theoretical analysis to confirm where move within Brillouin zone strength breaking increases, ...

Astrobiology is the study of the origin, evolution, distribution, and destiny of life in the universe. The field uses many scientific disciplines and spectrometric technologies to address these important issues. While questions about life in the universe have existed as long as man has looked up at the stars, advances in science and spectrometry in the past few decades make it possible for us t...

Manganese zinc ferrite nanoparticles (MZF NPs) were synthesized by using a direct, efficient and environmental friendly hydrothermal method. To improve the colloidal stability of MZF NPs for biomedical applications, NPs were coated with chitosan by ionic gelation technique using sodium tripolyphosphate (TPP) as crosslinker. The synthesized NPs were characterized by X ray diffraction (XRD) analy...

toxicity bioassays are important tools to determine biological effects of chemical agents on species. the questions remained on, what effects have been imposed on each of the different molecular site of cells by chemical exposure and how to find a pattern for chemical toxicity. to address the questions, hepg2 cell lines were exposed to the different concentrations of cisplatin for 24 hours to r...
