A simple method for fabrication of highly ordered gold nanorod film is introduced in this article. The procedure is based on thermal evaporation of gold into a porous anodic alumina film (PAA). The PPA film was fabricated by combining the hard and mild anodization. This combination effectively decreases the processing time of fabrication of highly ordered porous anodic alumina film with c...

Auditory-visual looming (the presentation of objects moving in depth towards the viewer) is a technique used in film (particularly those in 3D) to assist in drawing the viewer into the created world. The capacity of a viewer to perceptually immerse within the multidimensional world and interact with moving objects, can be affected by the sounds (audio cues) that accompany these looming objects....

The works make the ‘present’ image from what is normally absent. The underlying structural principles of video frames and encoding are the bases of the developing picture. In this sense, the ‘now’ of a video image is multidimensional and variable; past, present and future are the simultaneous condition of a single moment (unlike film frames, which can be isolated as spatially and temporally dis...

in this paper a chemical deposition procedure for the preparation of lead sulfide thin film ispresented. the details of the preparation method are described. the influence of hydrazine hydrate onthe microstructure and deposition rate of lead sulfide thin film has been investigated. the concentrationof the lead ions in the deposition bath decreases more slowly when the hydrazine hydrate is added...

We examine the photo-assisted polarization loop in a BiFeO3 thin film under UV light illumination. BiFeO3 thin film prepared by pulsed laser deposition method onto the BaTiO3 thin film and the polarization behavior has been measured under poling voltage. Our results show the engineered polarization due to controllable schottky barrier under inverse poling voltage. This control on schottky barri...

Introduction: Dental caries is dramatically common among people. The aim of this study was to evaluate the agreement of paper prints and film prints and monitor in detection of dentinal caries in digital panoramic radiography. Materials and methods: In this analytical study, radiographic images of 150 patients referred to a private clinic and who needed panoramic radiographs for various rea...

the conducting polymer films have been widely applied in the field of electrochemistry owing to their goodstability, permselectivity, unique physical and chemical properties. a novel nano-au/poly (4-aminobenzoicacid) (paba) film modified carbon paste electrode was fabricated for sensitive detection of acetaminophenin this paper. the paba film and nano-au/paba film were characterized by scanning...

Introduction: Bite wing radiographs are indicated in children with closed posterior contacts. Given the fact that nowadays bitewing radiographs are taken using both paper loop and film holder, the aim of this study is the evaluation of acceptance and diagnostic quality of two methods. Materials and Methods: This study is a sort of diagnostic accuracy test that was performed on 20 6-8 year old ...

background:  radiochromic film is used for radiation dose measurement, xr-rv3 is used in fluoroscopy and ebt2 film in radiation therapy. the aim was to determine if the dosimetric properties of these two films are comparable in megavolt photon beams. materials and methods: comparison measurements included: calibration curves, heterogeneous phantom dose profiles, and nasopharynx dose distributio...
