In the following we will deal with the experiments we have performed in order to study the ELDRE response of RHBip1 technology. The basic idea is to irradiate devices at high temperature to enhance the damage, as suggested in [1]. Of course we will also try to understand this behavior using the model described in Chapter 5. Eventually we will compare ETI results with LDR ones to see if the ETI ...

Introduction: Irradiation of intervention strategies in order to effectively control food-borne pathogens are microorganisms that reduce microbial load and increase the shelf-life. Methods: In this study, ostrich meat with electron beam 1.5, 3 and 5 kGy doses treated and were stored in temperature 1 ± 4° C for 15 days. With 5 day intervals after irradiation, chemical and organolep...

Introduction: hyperthermia using different methods such as microwave and magnetic waves is one of the methods to treat cancer. In this method, iron and magnetic nanoparticles are used to increase the temperature and increase the effect of hyperthermia as auxiliary treatment with chemotherapy and radiotherapy. In this study, the role of iron and magnetic nanoparticles have been ...

thermal barrier coatings (tbcs) are used to provide thermal insulation to the hot section components of gas turbines in order to enhance the operating temperature and turbine efficiency. hot corrosion and thermal shocks are the main destructive factors in tbcs which comes as a result of oxygen and molten salt diffusion into the coating. in this thesis atmospheric plasma spraying was used to dep...

For estimating the annual mean of daily solar irradiation in plateau mountainous regions, observed data from 15 radiation stations were used to validate different empirical estimation methods over the Tibetan Plateau. Calibration indicates that sunshine-based site-dependent models perform better than temperature-based ones. Then, the highly rated sunshine-based Ångström model and temperature-ba...

Quality-control dosimetry is important to the routine operation of a radiation processing facility. For many applications this dosimetry must be traceable to a national primary standard. After irradiation at an industrial facility, National Institute of Standards and Technology (NIST)-supplied transfer dosimeters are certified by measurement and dose interpolation from the NIST calibration curv...

AIM To study the optical properties of human normal small intestine tissue at 476.5 nm, 488 nm, 496.5 nm, 514.5 nm, 532 nm, 808 nm wavelengths of laser irradiation. METHODS A double-integrating-sphere system, the basic principle of measuring technology of light radiation, and an optical model of biological tissues were used in the study. RESULTS The results of measurement showed that there ...

• A phase-field model is developed for He bubbles in Fe under a temperature gradient. move up the thermal gradient with velocities faster than UO 2 . Stresses matrix from bubble pressure have negligible effect on velocity. Residual stress can modify via modified diffusion. parameterized to study of elastic stresses migration gas caused by and residual are considered. The dependence velocity mag...
