The purpose of this study was to assess color alteration of the paints used for iris painting in artificial eyes. Five disks of heat cured acrylic resin were confectioned by microwave energy for each paint analyzed, in a total of 40 specimens. Each specimen consisted of a colorless acrylic resin disk and another of equal size, of scleral white colored acrylic resin, with the painting interposed...

Uniform gadolinium oxysulfate (Gd2O2SO4) hollow spheres were successfully fabricated by calcination of corresponding Gd-organic precursor obtained via a facile hydrothermal process. The Gd2O2SO4 hollow spheres have a mean diameter of approximately 550 nm and shell thickness in the range of 30-70 nm. The sizes and morphologies of as-prepared Gd2O2SO4 hollow spheres could be deliberately controll...

In this paper, the four parameters of plasma (density electron, temperature length Debye and frequency plasma) are studied. Optical emission spectroscopy method is utilized to study sphere (ND). The spectrum with different values energy, Zn Nio at percentage (X=0.1, 0.3, 0.5) were recorded. spectroscopic for these mixing under vacuum pressure down P=2.5×10?2 mbar. results electron X=0.1 range (...

In this presented work, pure and holmium, niobium, holmium–niobium co-doped titanium dioxide nanopowders were synthesized by the sol–gel method. Their morphological, structural, optical, photocatalytic properties analyzed scanning electron microscopy, X-ray diffraction, UV–visible spectrophotometer. The activities of examined using ultraviolet light. results have shown that doping both with a s...

CuAlS2  Chalcopyrite  nanocrystalline  are  synthesized  with  facile method.  The  heat  arrested  solvothermal  method  for  synthesize nanocrystalline  were  investigated.  The  time  duration  of  synthesis, temperature of solution and metal salts to solvent molar ratio can be parameters  that we are  studied. The nanoparticles were  synthesized with CuCl, AlCl3 and  thiourea (SC(NH2)2...

Carbon nanotube-In2O3 nanocomposites were synthesized by sol-gel method with the help of ultrasonic radiation. The samples were characterized by X-ray diffractometer, transmission electron microscopy and energy dispersive spectrometer. The UV absorbing properties were detected by the UV spectrophotometer. Photo degradation of methylene blue in aqueous solution was investigated by using CNT/In2O...

BACKGROUND Adaptation is an evolutionary process in which traits in a population are tailored by natural selection to better meet the challenges presented by the local environment. The major discussion relating to natural selection concerns the portraying of the cause and effect relationship between a presumably adaptive trait and selection agents generating it. Therefore, it is necessary to id...

Fluoropyruvate has been shown to interact with thiol compounds (Avi-Dor & Mager, 1956a; Peters & Hall, 1957). Its inhibitory action on the respiration of mitochondria (Avi-Dor & Mager, 1956b; Chari-Bitron & Avi-Dor, 1958) and of tissue celLs (Traub & Ginzburg, 1959) is presumably due to combination with thiol groups. We have observed that, during an incubation of the product formed between glut...

The present study was undertaken to study the sunscreen activity of herbal formulation. There is no evidence of the sun protection factor (SPF) studies on essential oil of Calendula flowers (Calendula officinalis L., Asteraceae). The study investigates the in vitro SPF by ultraviolet specrtophotometry method of Calendula flower oil in a cream formulation. Calendula oil was isolated by Clavenger...

This research is aimed to improve the oxytetracycline production from Streptomyces rimosus. Five relatively high oxytetracycline yielding strains were obtained by nitrosoguanidine mutation of the protoplast of initial oxytetracycline producing strain Streptomyces rimosus JH and then subjected to genome shuffling as parental strains. The protoplasts of the five parental strains were prepared and...
