Although luminescence of water lower in energy than the Cerenkov-light threshold during proton and carbon-ion irradiation has been found, phenomenon not yet implemented for Monte Carlo simulations. The results provided by simulations lead to misunderstandings physical optical imaging irradiation. To solve problems, as well clarify light production water, we modified a simulation code include from compared them with experimental water. We used GEANT4 emitted using scintillation process while...
A 48-year-old woman with late infantile onset mental retardation developed megacolon. Although the patient had no typical clinical features of Hirschsprung disease–mental syndrome, a new 3–base pair deletion, eliminating an Asn, was identified in responsible gene <i>ZFHX1B</i>. This suggests that screening for <i>ZFHX1B</i> mutations is warranted even absence syndrome.
Neutron spectrum analyses of spallation neutrons are conducted in the accelerator-driven system (ADS) facility at Kyoto University Critical Assembly (KUCA). High-energy protons (100 MeV) obtained from fixed field alternating gradient accelerator injected onto a tungsten target, whereby generated. For neutronic characteristics neutrons, reaction rates and continuous energy distribution measured by foil activation method an organic liquid scintillator, respectively. Numerical calculations...
We have developed a remote scintillation detector using CCD spectrometer and red-emitting scintillator coupled with 20 m optical fiber for ultra-high-dose conditions. Gamma rays were detected conventional deep-red-emitting ruby Cs2HfI6, which is novel material 700 nm red emission high light output. The scintillators irradiated gamma from 60Co source under an effective dose rate ∼0.002 to ∼1 kSv h−1. integrated area of the Cs2HfI6 spectra was larger than that ruby, good linearity signal as...
Large-scale cell suspension culture technology opens up opportunities for numerous medical and bioengineering applications. For these purposes, scale-up of the system is paramount. initial small-scale culture, a simple static (SSC) generally employed. However, sedimentation due to lack agitation limits volume feasible SSC. Thus, when scaling up, suspensions must be manually transferred from flask another vessel suitable agitation, which increases risk contamination human error. Ideally,...
Nuclear power plants (NPPs) are globally important sources of clean energy. However, high operation and maintenance (O&M) costs one the factors hindering development NPPs. In this study, we focused on a digital algorithm for ex-core instrumentation systems (EISs) to reduce O&M costs, given that digitalization EISs is not progressing compared with other control in Specifically, developed pulse signal processing EISs, which traditionally require significant amount hardware efforts. Our...
A new red-emitting halide scintillator Rb <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> HfI xmlns:xlink="http://www.w3.org/1999/xlink">6</sub> was developed using the vertical Bridgman furnace and quartz ampoule. Under X-ray irradiation, had a broad emission band of around 725 nm. The light output energy resolution were determined to be ~40000 photons/MeV ~7.4% (full-width at half-maximum 662 keV), respectively. Since red photons are...
Abstract The internal exposure of workers who inhale plutonium dioxide particles in nuclear facilities is a crucial matter for human protection from radiation. To determine the activity median aerodynamic diameter values at working sites real time, we developed high-resolution alpha imager using ZnS(Ag) scintillator sheet, an optical microscope, and electron-multiplying charge-coupled device camera. Then, designed applied setup to measure particle identify locations individual time....
Background: Measuring the energy spectrum of γ rays to assess exposure dose and identifying leaked radioisotopes at accident site surrounding environment is necessary in case an involving leakage radioactive material a nuclear power plant or radiation-related facility.High-purity germanium semiconductor detectors are utilized for γ-ray spectrometry due their high resolution, but they exhibit initial operational cost need cooling mechanism. Materials Methods:We improved unfolding method...
15088 Background: A 5-fluorouracil (5-FU)/cisplatin (CDDP)-based chemoradiotherapy (CRT) was proposed for esophageal cancer patients. Currently, there is an urgent need to establish a methodology decide which preferable patient, i.e., surgical treatment or CRT, especially Stage II III tumors defined as resectable. This study performed find the genetic factors predictive of clinical outcome 5-FU/ CDDP-based CRT in Japanese patients with locally advanced squamous cell carcinoma (ESCC)....
Suspension culture is an essential large-scale cell technique for biopharmaceutical development and regenerative medicine. To transition from monolayer on the surface of a flask to suspension in bioreactor, pre-specified number must first be reached. During this period preparation culture, static generally performed because medium volume not large enough use paddle circulate medium. However, drawbacks method include sedimentation, leading high density near bottom resulting oxygen nutrient...
