  • Food Irradiation Research Paper

    IRRADIATION Food irradiation is the processing of food products by ionising radiation in order to control food borne pathogens, reduce microbial load and insect infestation, inhibit the germination of root crops, and extend the durable life of perishable produce (International Consultative Group, 1991). Application of ionizing radiation results in the radiolysis of water. This triggers the development of species such as OH−, hydrated electron and H+, which can then induce several chemical…

  • Analysis Of Three Bentonite Materials

    Analysis Three Bentonite properties, which makes it a unique buffer material for nuclear disposal applications are discussed in the following: 1) Thermal conductivity Thermal conductivity is the rate at which heat can be transferred through a certain material. It is also expressed as the flux of heat, which flows per unit time through a unit distance with a temperature gradient of one degree per unit area. Thermal conductivity, like other tensor parameters, has different values in different…

  • Case Study: A Career As A Surgical Oncologist

    Surgical takes patients into surgery to remove any object that is obstructing the body. Medical gives medicine and treatments at the first stage of cancer. Then there is radiation, which is given at a higher stage of cancer and it produces x-rays and radionuclides throughout the body. These specialists not only save lives, they also save worlds. Surgical, medical, and radiation oncologists make this world a better place and we need more to sustain the world. Although there is multiple types of…

  • Advantages Of Anatomical And Metabolic Imaging

    accurately registered anatomic and functional images can be acquired in a single examination Current designs constitute a CT scanner in tandem with a PET scanner, with a common patient bed for both systems. Although in most designs, the scanner appears externally to be a single device, internally there is little or no mechanical integration (Fig.12) Limitations and advantages of anatomical and metabolic imaging: Limitations of anatomical imaging include; inability to determine if a mass is…
