In recent decades, most of researchers in pharmaceutical preparations have focused increasingly on new formulations that control the site and amount of drug delivery. Mucoadhesive dosage forms are available for systemic or local treatment. The mucoadhesive dosage forms are introduced in various forms such as tablets, gels, ointments, patches and polymeric films. For buccal wound and inju...

The use of mammography film-screen is limited in general radiography. The purpose of this study was to compare the effectiveness of mammographic film-screen and standard film-screen systems in the detection of small bone fractures. Radiographs were taken from patients' extremities and neck areas using mammography film-screen and standard film-screen (n=57 each). Fourteen other radiographs were ...

introduction: radiography is one of the most important diagnostic methods for evaluation of dental caries. on the other hand, the least amount of radiation along with high quality is a main gold standard. the purpose of this study was to compare the diagnostic accuracy of primax, insight radiographic films, and direct digital images (schick cmos-aps), in detection of interproximal natural carie...

background: ebt and ebt3 radiochromic films have been used in radiotherapy dosimetry for years. objective: the aim of the current study is to compare ebt and ebt3 radiochromic films in dosimetry of radiotherapy fields for treatment of parotid cancer. methods: calibrations of ebt and ebt3 films were performed with identical setups using a 6 mv photon beam of a siemens primus linac. skin dose was...

The effect of surface bond-order loss on the classical resistivity of metallic polycrystalline thin films is studied. The potential barriers due to grain boundaries considered here contain square-well depressions on both sides taking into account the effect of surface bond-order loss for the grains in a film. Electron scattering by film surfaces is also considered following the lines of Fuchs’ ...

Thin films of LaS were prepared by using spray pyrolysis technique at 270 0 C and thickness were varied by changing the concentration of reactant solution. The films were optically characterized and their variations with film thickness were studies. It was found that thickness can be tuned by varying concentration of reactant solution. The band gap was found to vary between 2.35eV to 2.50eV. Th...

T he stage was set for exciting advances in dentistry in the 1950s and 1960s when prototypes of computer-aided design (CAD) and computer-aided manufacturing (CAM) were introduced into industrial settings. 1 In those applications , the geometry of the " parts " was simpler than that generally needed for dental restorations , but the same techniques could be applied to creating dental crowns. Ear...

Kodak X-Omat V radiographic film has been tested for its polarization properties when using polarized and non-polarized light sources and detectors. The radiographic film has been shown to produce a relatively small but not negligible (less than 5%) variation in 90 degrees cycles in measured optical density within the visible spectrum when the light source is fully linear polarized and the film...

The purpose of this study was to determine the need for supplemental periapical radiographs in planning restorative services and pulp treatment for primary molars when a child’s bite-wing radiographs were taken with No. Oor No. 2-size film. Forty-eight good quality bite-wing radiographs were selected from patients 5-7 years of age and sorted into four groups containing 12 films classified accor...
