  • Analysis of the conditions of use of the high-frequency power transformer and design principles

    According to the conditions of use of the high-frequency power transformer (transformer manufacturers) analysis, the overall two-fold: the feasibility and electromagnetic compatibility. Only pay attention to the feasibility of environmental protection awareness, must pay attention to electromagnetic compatibility. Feasibility refers to the specific conditions of use, high-frequency power ...

  • More durable or more vulnerable? - Effect of nanoparticles on long–term performance of polymeric nanocomposites during UV exposure

    ZnO nanoparticle is being used as an inorganic UV absorber for polymers. However, the mechanism of how ZnO nanoparticles influence the photo degradation of polymersis is not well understood. This study has investigated the role of ZnO nanoparticles in the long–term performance of a polyurethane (PU) nanocomposite subject to UV radiation. PU samples containing different levels of ZnO nanoparticles ...

  • External and internal radiation doses due to alpha activity in Tafila district, Jordan

    Tafila district of Jordan is unique in the presence of phosphate mines and hot spa which are the major sources of natural radioactivity. Natural radionuclides transfer from soil to vegetables grown in the region, and become a part of people's food. In this study, 16 soil and vegetable samples from Tafila district were collected from eight locations. External absorbed dose rates were calculated to ...

  • Low doses of γ–radiation induce consistent protein expression changes in human leukocytes

    Twenty percent of cancer patients experience adverse effects after radiotherapy. The therapeutic doses are adjusted to the most sensitive individuals, resulting in a suboptimal dose for many patients. At present there is no screening system available to predict individual radiosensitivity. The main aim of this study is to investigate differences in protein expression pathways induced by low doses ...

  • Encoded photometric infrared spectroscopy

    General Principle The EP-IR system contains the encoder-spectrograph, as well as a real-time embedded micro-processor for signal analysis, data treatment, and Chemometrics (quantitative) analysis in a single small-footprint enclosure. Operation Principle An infrared polychromatic beam is emitted from an external source (e.g. glow bar) onto the sample. Then ...

  • Relationship between trace elemental composition in Fraxinus pennsylvanica bark and the incidence of some respiratory diseases in Cordoba, Argentina

    In order to evaluate the use of Fraxinus pennsylvanica as a biomonitor of trace elements and to investigate their relationship with the incidence of some respiratory diseases in children, bark samples of F. pennsylvanica were collected at ten sampling sites near healthcare centres in Cordoba city, Argentina, and analysed by Total Reflection X-ray Fluorescence with synchrotron radiation. Factor ...

  • Sensitivity of Cladonia substellata Vainio (lichen) to gamma irradiation and the consequent effect on limestone rocks

    The lichens play an important role in decomposition of the rocky substrate, through the chemical weathering of their substances. In this paper, we wanted to determine the influence of gamma rays on usnic acid production by Cladonia substellata. Samples of lichens were exposed to gamma rays from a Co-60 source, receiving different doses on gamma irradiator. After irradiation, the lichens were ...

  • Radiation-induced DNA damage in patients exposed to X-rays during cerebral angiography

    Population exposure to diagnostic and therapeutic ionising radiation is likely to increase worldwide, and this has raised concerns about the stochastic effects of low doses of radiation exposure. The present study was aimed to study the incidence of Chromosomal Aberrations (CAs) in patients exposed to low doses of X-rays during diagnostic interventional radiological procedures. Peripheral blood ...

  • Water disinfection by solar radiation in a green house effect device

    The water-borne diseases are major concerns in developing countries since they are the main cause of sickness and death among the population in rural communities. The traditional methods such as chlorination and the use of fuelwood to boil water has important environmental consequences and in some cases are rejected by population. The solar water heaters are considered as an effective, low cost ...

  • Chromosomal aberrations induced by a low dose of neutron irradiation and hyperthermia

    The purpose of this study was to investigate the effect of Hyperthermia (HT) on the Frequency of Chromosomal Aberrations (FCA) induced by a low dose of neutron irradiation. Blood samples were exposed to HT, 6cGy neutrons, HT + neutrons and neutrons + HT, and the FCA was scored in metaphase. HT alone at 41.5°C had no effect on FCA; however, the FCA was significantly higher at 43°C (p ...
