The basic optical properties and optical constants of the ionomer thin film have been investigated by means of transmittance and reflectance spectra. The real (n) and imaginary (k) parts of the complex refractive index and dielectric constant of the thin film were determined. The oscillator energy Eo, dispersion energy Ed and other parameters have been determined by the Wemple– DiDomenico metho...

I . Two experiments were carried out with sheep and cattle receiving high-concentrate rations to estimate the amount of digestion taking place in the rumino-reticulum and omasum. Two techniques were used for the collection of samples of abomasal contents. In the experiment with sheep, animals were slaughtered at different times after feeding and samples of digesta were collected. In the experim...

Introduction: A study was performed to evaluate radiation dose distribution and dose gradient around cylindrical applicators for high-dose-rate (HDR) brachytherapy systems with 192Ir, 60Co brachytherapy source applied for rectal and vaginal cancers treatments.   Materials and Methods: Two additional computed tomography (CT) based plans were generated using a ...

The present work has used an accelerated test method, based upon cyclic-fatigue testing using a fracture-mechanics approach, to study the durability of organosilanepretreated joints which were adhesively-bonded using a hot-cured epoxy-film adhesive. The silane primer investigated was γ-glycidoxypropyltrimethoxysilane (GPS). The cyclic-fatigue tests were mainly conducted in (a) a ‘dry’ environme...

Many researchers have reported on obtaining TiO2 thin films, using different methods [1-7]. These extensive studies on TiO2 have been due to the importance of these films in variety of applications including low-loss, low-scatter optical coating for visible and near infrared optics [8-11] and electrical devices [12,13]. These applications have stimulated a considerable amount of activity in fab...

Zinc Sulfide (ZnS) thin films were deposited on glass substrates at the pressure of 10-6 mbar by thermal resistor evaporation technique. The effects of annealing on the structural, optical properties of ZnS films were studied. Crystalline ZnS films have been analyzed by X-ray diffraction. Only cubic phase with the preferred (111) plane was found in ZnS films. Optical characteristics were studie...

CP titanium was polished with a colloidal sitica suspension and chromic ox{de slurry under low and high pressures. The polisheti surfaces wer'e characterized by means of EI]MA and XPS. Irrespeetive of polishing pressure, colloidal silica suspension suecessfully created a mirror-Iike surface that was clean at EPMA level, However, XPS detected a small amount of silicon on the outermost surface. O...

Nisamycin, a novel manumycin group antibiotic, was isolated from the culture broth of Streptomyces sp. K106. Structural elucidation of nisamycin was achieved by detailed NMR spectral analyses and comparison of the NMR data of nisamycin with those of other manumycin group antibiotics. The structure was confirmed by chromic acid oxidation. The absolute stereochemistry of nisamycin was determined ...
