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...
This study is to examine the educational status of the art of film as to describe the ways of achieving the concept of consciousness as the requirement for education. Findings show that through exploring a film, as to come up with consciousness, it is possible to have inductions and deductions from a film and its audience. With this presumption that a film is similar to a content of the textboo...

E * - Assistant professor of Oral Radiology Dept. Faculty of Dentistry Yazd University of Medical Sciences. ** - Dentist. Background and aim: In dental radiography, there are specific potentials to transmit infection. T...
carboxymethyl cellulose (cmc)-polyvinyl alcohol (pvoh) blend film was produced through casting. cellulose nanowhisker (cnw) was produced by means of acid hydrolysis of cotton linter and cmc-pvoh-cellulose nanowhiskers through which fully degradable bionanocomposites were prepared. prepared nanowhisker suspension contained rod like particles averaging lengths of 240 nm and diameters of 13 nm. an...
Background and objectives: Soils are one of the largest carbon stores in the biosphere with the highest carbon storage potential to mitigate the effects of climate change. The aim of this study was to investigate different land uses on carbon storage and other physical, chemical and biological characteristics of soil in Shahriar. For this purpose, rangelands including 26-year-old, 16-year-old a...
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...
ABSTRACT: The use of new compounds to increase the shelf life of more perishable foods based on nanoparticles and biodegradable polymers have been developed in packaging. Chitosan (Cts) is a natural biopolymer with excellent biodegradability and nontoxicity and antibacterial effect. In this research antibacterial copper nanoparticles (CuNPs) were incorporated in the biodegradable chitosan matri...
A common method of silage production in Europe is based on the use cylindrical bales wrapped with polyethylene films. In this study, several modifications composition these films were tested for their impact microorganisms involved ensiling process. Different additives, including nanosilver particles and microcellulose, analyzed upon first stage experiment. second stage, usability recycled as a...
Agriculture is a major source of global greenhouse gas emissions. Approximately 1/3 vegetables in China are produced greenhouses. However, the effects different irrigation strategies and plastic film (PF) mulching combinations on N2O emissions tomato fruit yields greenhouses unclear. The aims this study were to explore micro-sprinkler under (MSPF), drip (DIPF) (MSI) soil nutrients, enzyme activ...
The antimicrobial property is the key feature of active packaging. Biological macromolecules such as tannic and gallic acids are naturally found in plants tea, fruits, berries, grapes. incorporation acid (TA) (GA) biodegradable polymer blend Poly Lactide-Poly (Butylene Adipate-Co-Terephthalate) (PLA-PBAT) was used this study to assess potential TA GA (10 wt%) composite films showed a 65%–66% in...
