in this study, antimicrobial effects of zataria multiflora boiss added to sodium caseinate film on four bacterial species: staphylococcus aurous, escherichia coli, bacillus subtilis and salmonella intertidis was investigated. disk diffusion method was used to study the antimicrobial activity of zataria multiflora boiss in sodium caseinate film. 9 mm disks were prepared from produced films with ...

Dye-sensitized solar cells (DSSCs) are categorized as some of inexpensive thin-film solar cells. The basis and foundation of these cells is a semiconductor that consists of an electrolyte and a light-sensitive anode. Titanium dioxide (TiO2) is a semiconductor that plays the role of anode and is the main constituent of these cells. In this paper, we have addressed the functionality and performan...

   High transparent conductive indium tin oxide/titanium dioxide (ITO/TiO2) nanostructured thin film is prepared by sol-gel dip-coating technique. This method yielded monodisperse ITO nanoparticles with mean diameter of 12 nm. The atomic composition of the Sn within the ITO structure changed from 0-20 wt.%. Through controlled annealing temperature at 550 oC, the result...

Introduction: Due to the advantages of sourdough, its film production for food packaging could be interesting. This study aimed to evaluate the influence of probiotic sourdough based edible film covered on set yogurt and subsequent changes during post fermentation storage. Materials and Methods: The parameters examined included changes to the fermentation characteristics (pH, and viable counts...

In the current study, the effects of Casimir force and squeeze film damping on pull-in instability and dynamic behavior of electrostatically actuated nano and micro electromechanical systems are investigated separately. Linear elastic membrane theory is used to model the static and dynamic behavior of the system for strip, annular and disk geometries. Squeeze film damping is modeled using nonli...

a title sequence is the beginning and the audience’s first center of attention to the film, in which the film’s title, key production and cast and crew along with some special notions related to the film’s content are introduced through typography. a film title sequence may include live action, animation, music, still images and graphics. with the invention of the cinematograph, in order to ide...

A single calibration film method was evaluated for use with intensity-modulated radiation therapy film quality assurance measurements. The single-film method has the potential advantages of exposure simplicity, less media consumption, and improved processor quality control. Potential disadvantages include cross contamination of film exposure, implementation effort to document delivered dose, an...
