This study aimed to obtain and characterize an RU-β-CD complex in the context of investigating the possibility of changes in the solubility, stability, antioxidative and microbiological activity as well as permeability of complexated rutin as against its free form. The formation of the RU-β-CD complex via a co-grinding technique was confirmed by using DSC, SEM, FT-IR and Raman spectroscopy, and...

This study aims to prove the complexation of cefpodoxime proxetil (CP) by hydroxypropyl-βcyclodextrin (HP-βCD) in the presence of sodium carboxymethyl cellulose (Na CMC), and investigates the permeability of CP in the complexes. The CP–HP-β-CD complex was prepared by kneading method and was characterized by Scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FTIR) and D...

The optical and electrical properties of zinc-doped Cz p -GaAs have been studied. Reflection spectra ten specimens taken in the mid-IR region. Van der Pau galvanomagnetic, resistivity Hall coefficient measurements carried out for same (all were at room temperature). reflection processed using Kramers–Kronig relations, spectral dependences real imaginary parts complex dielectric permeability cal...

A coaxial transmission line was constructed, characterized, and calibrated for the frequency dependent measurement of complex relative permeability (l r) and complex permittivity (e r). The permeability of Ni powder with a grain size of < 1 lm was measured as a function of packing density to verify the system performance. 8–10 nm diameter Co nanoparticles were synthesized, dried to a powder, an...

Determination of porosity, permeability, and pore volume compressibility of reservoir rocks and those variations with effective stress changes are of great interest in petroleum engineering. This paper has studied the influence of pore types of carbonate reservoir rocks on pore volume compressibility as well as Klinkenberg permeability and porosity at different stress values. In the current stu...

the complex formation reaction between iodine with tetrabutylammonium halides (tbax) has been studied spectrophotometrically in chloroform solution at 25ºc. various aspects of the spectra of iodine in the presence of various concentration of different tetrabutylammonium halides have been discussed in terms of electronic specifications of iodine and halides. in the case of tetrabutylammonium iod...

This paper describes a novel energy-based probabilistic distribution that represents complex-valued data and explains how to apply it to direct feature extraction from complex-valued spectra. The proposed model, the complex-valued restricted Boltzmann machine (CRBM), is designed to deal with complex-valued visible units as an extension of the wellknown restricted Boltzmann machine (RBM). Like t...
