BACKGROUND The aim of this study was to assess and compare the effective doses (ICRP 103) in the ankle region of X-ray imaging resulting from a multi slice computed tomography (MSCT) device, two cone beam CT (CBCT) devices and one conventional x-ray device. METHODS Organ dose measurements were performed using 20 metal oxide field effect transistor (MOSFET) dosimeters that were placed in a cus...

INTRODUCTION Artificial models can be useful at approximate and qualitative research, which should give the preliminary results. Artificial models are usually made of photo-elastic plastic e.g.. juvidur, araldite in the three-dimensional contour shape of the bone. Anatomical preparations consist of the same heterogeneous, structural materials with extremely anisotropic and unequal highly elasti...

PURPOSE This in vitro study intended to investigate the mechanical and thermal characteristics of Valplast, and of polymethyl methacrylate denture base resin in which different esthetic fibers (E-glass, nylon 6 or nylon 6.6) were added. MATERIALS AND METHODS FIVE GROUPS WERE FORMED: control (PMMA), PMMA-E glass, PMMA-nylon 6, PMMA-nylon 6.6 and Valplast resin. For the transverse strength test...

Agomelatine is a melatonergic anti-depressant. A stability-indicating high performance liquid chromatographic technique was developed for the determination of Agomelatine in pharmaceutical formulations. Chromatographic separation was achieved on Shimadzu Model CBM-20A/20 Alite, using Zorbax extended-C18 column (150 × 4.6 mm i.d., 5 μm particle size) with a mixture of 0.1% ammonium formate and a...

Thin alumina films, deposited at 280~ by low-pressure, metal-organic, chemical-vapor deposition on stainless steel, type AISI 304, were annealed at 0.17 kPa in a nitrogen atmosphere for 2, 4, and 17 hr at 600, 700, and 800~ The effect of the annealing process on the adhesion of the thin alumina films was studied using a scanning-scratch tester, type SST-IO1, developed by Shimadzu. The best mech...

Vacuum evaporated crystalline films of Zinc Selenide (ZnSe) have been characterized by using optical spectroscopy (especially transmission and absorption spectra). Thin films of ZnSe have been deposited by vacuum evaporation technique on highly clean glass substrates and their optical properties such as refractive index (n), extinction coefficient (k), and energy band gap have been studied. The...

A Shimadzu high performance liquid chromatography – ion trap – time of flight mass spectrometer (LCMS-IT-TOF) was used to aid in the identification of anthocyanin species in rose petals. The effects of varying the parameters which control the collision energy and the collision gas were observed on cyanidin-3,5-diglucoside and its related mono-glucoside and anthocyanidin fragment signals. Furthe...

Methods Verum (aconitum 30c, calcium carbonate/quercus e cortice) and placebo globules used in two previous clinical trials were dissolved in distilled water at 10mg/ml 20-23 hours prior to the measurements. Absorbance was measured at 190 – 340nm with a Shimadzu UV-1800 double beam spectrophotometer. Duplicates of each sample were measured in a randomized order 4 times on each of the 5 measurem...
