objectives: the optimal goal of radiography is to provide high-quality diagnostic images with the least patient radiation dose. the aim of this study was to evaluate the accuracy of cone-beam computed tomography (cbct) and intraoral photostimulable phosphor plate (psp) digital and film-based conventional radiography for detection of artificial cancellous bone defects. materials and methods: fiv...

background detergents and difficulties of their presence in the water and wastewater cause various problems such as foam production, anomalies in the growth of algae, and accumulation and dispersion in aqueous environments. objectives the aim of this study was to examine and compare the moving bed biofilm reactor with another reactor without media (carries) for anionic surfactants removal. mate...

BACKGROUND Although two-dimensional (2-D) monolayer cell cultures provide important information on basic tumor biology and radiobiology, they are not representative of the complexity of three-dimensional (3-D) solid tumors. In particular, new models reproducing clinical conditions as closely as possible are needed for radiobiological studies to provide information that can be translated from be...

INTRODUCTION AND METHODS. Rat barrel cortex undergo plastic changes during sensory experience (3). Twenty four hours o f "pairing" o f untrimmed whiskers leads to short lasting changes in supraand infragranular layers o f corresponding cortical columns. In order to reveal the early dynamics o f this process we studied evoked responses recorded by bipolar electrodes chronically implanted in the ...

Bean plataspid, Megacopta cribraria (F.) (Hemiptera: Plataspidae), was first reported in northeastern Georgia in the fall of 2009 (Eger et al. 2010), and since then has spread throughout Georgia and into North Carolina, South Carolina, Alabama, Virginia, Mississippi and Florida (Roberts 2011; Suiter et al. 2010a, 2010b; http://www. kudzubug.org/distribution_map.cfm; Medal et al. 2013). This pla...

Background: Due to volatility of radioactive iodine solutions, usually internal exposure would occur in personnel that are working in nuclear medicine centers. The activities in the thyroid of individual s who work in nuclear medicine centers of North West provinces of Iran were measured using NaI (Sodium Iodide) detectors. In every center, nearly 40 - 500 mCi of 131 I and 50 - 600 μ Ci of 125 ...

The recent development of laser light probes for stress wave measurements has aided our understanding of acoustic emission and ultrasonic signals by allowing quantitative measurements of stress waveforms. This paper reports on applications of the laser interferometer probe for surface detection of stress waves and the laser transmission probe for sensing of stress waves inside transparent mater...

Introduction: High-energy beams of protons offer significant advantages for the treatment of deepseated local tumors. Their physical depth-dose distribution in tissue is characterized by a small entrance dose and a distinct maximum -Bragg peak- near the end of range with a sharp fall-off at the distal edge. Alongside its advantages there are some point that they need to meticul...

The discusser wishes to congratulate the authors for their excellent paper. He would like to discuss some possible drag reduction effects. The discusser has reanalyzed the authors' data assuming quasi-uniform flows at the end of the channel. For the clearwater flow experiments (runs C-1 and C-2), the data suggest an equivalent roughness height k, of the flume (smooth plexiglass) between 0.15 mm...
