Box 100 A-1400 Vienna, Austria FOREWORD The third Research Coordination Meeting (RCM) of the Coordinated Research Project (CRP) on Radiometric Methods for Measuring and Modeling Multiphase Systems towards Industrial Processes was held at the International Atomic Energy Agency (IAEA) Head Quarters, Vienna, Austria from 11-15 April 2016. The Chief Scientific Investigators of all research contracts and agreements under the CRP participated in the meeting. Four research agreement holders from Norway, France, Poland and Korea provided assistance to the other RCM participants with their expertise and know-how. The twelve research contract holders from Brazil, Cuba, China, Ghana, Malaysia, Morocco, Pakistan, Poland, Tunisia, Vietnam, India and Peru are with recognized experience in radiotracer and nucleonic measurement systems technologies. Multiphase flow systems are widely used in industrial and environmental processes, and widespread throughout chemical processing, mineral processing, oil production, wastewater treatment, sediment and solids transport, and many others. Optimized design and scale-up of these multiphase flow systems are important in ensuring enhanced performance, economic viability and environmental acceptability. The third RCM is organized to make a final review of the activities performed and progress achieved by all the participants of CRP, to draft and adopt the final meeting report and to finalise the CRP document to be published as a Radiation Technology Series.

Different aspects of industrial radiotracer technology for troubleshooting, process control and optimization are evaluated through an exhaustive literature survey. The review covers the advantages of radiotracers, most commonly used radiotracers in industry for specific studies, applications of radiotracer techniques in various chemical industries, the design of radiotracer technology experiments, radiation detection and data acquisition in radiotracer technology as well as radiological safety aspects. Two industrial radiotracer techniques of residence time distribution (RTD) measurements and radioactive particle tracking (RPT) are discussed. The design of radiotracer technology experiments are also divided into two categories - radioactive particle tracking applications and residence time distribution applications. Keyword: Industrial radiotracer, Industrial process, Process optimization, Residence time distribution, Radioactive particle tracking.

One limitation of this method is that only one radioactive atom is linked to each antibody and the deposited dose is often insufficient to eradicate solid and radioresistant tumors. In a previous study, simulations with the Monte Carlo N-Particle eXtended code showed that physical doses up to 50 Gy can be delivered inside tumors by replacing the single radionuclide by a radioactive nanoparticle of 5 nm diameter containing hundreds of radioactive atoms.

    26 May 2011 The Manager Company Announcements Office Australian Securities Exchange Limited 20 Bridge Street Sydney NSW 2000 Managing Directors Report Good morning ladies and gentlemen. As your Managing Director I warmly welcome you to Cyclopharm’s 2011 Annual General Meeting located here on the beautiful campus of Macquarie University, both the home of Macquarie University Hospital and The Australian School of Advanced Medicine. This is our first AGM located in New South Wales. In having the meeting here your board believed it was an ideal opportunity to show you the fruits of our labor. Across the street is located a couple of other firsts as well. Located on Basement 2 is our first cyclotron facility, CycloPet, and on the ground floor you can find our first medical imaging joint venture, Macquarie Medical Imaging. Following the formal meeting today, I welcome you all to join me on a tour of the facilities that your continued support has made possible. I am certain you will be impressed with what you see. Since 1986, our company has been saving lives every day. Your company was founded and continues to leverage off the global success of Technegas; however, the company’s transformation that we delivered in 2010 through diversification can best be summarised by stating that we are no longer a one product company. In addition to Technegas, we are now involved in the radiopharmaceutical production of isotopes used in Positron Emission Tomography or PET. The third development in our diversification evolution is our involvement in the Joint Venture MMI, a comprehensive imaging practice that also includes interventional radiology.

Box 100 A-1400 Vienna, Austria FOREWORD The first Research Coordination Meeting (RCM) of the Coordinated Research Project (CRP) on Radiometric Methods for Measuring and Modeling Multiphase Systems towards Industrial Processes was held at the headquarters of the International Atomic Energy Agency (IAEA) in Vienna on 15-19 October 2012. The Chief Scientific Investigators of all research contracts and agreements under the CRP participated in the meeting. Six research agreement holders from Norway, France, Poland, Germany, USA and Korea provided assistance to the other RCM participants with their expertise and know-how. The twelve research contract holders from Brazil, Cuba, China, Ghana, Malaysia, Morocco, Pakistan, Poland, Tunisia, Vietnam, India and Peru are with recognized experience in radiotracer and nucleonic measurement systems technologies. Multiphase flow systems are widely used in industrial and environmental processes, and widespread throughout chemical processing, mineral processing, oil production, wastewater treatment, sediment and solids transport, and many others. Optimized design and scale-up of these multiphase flow systems are important in ensuring enhanced performance, economic viability and environmental acceptability. The fluid-dynamic properties of such systems are not yet well understood, which makes the prediction of important process parameters such as flow rate, phase distributions, flow pattern, velocity and turbulent parameters a challenging task. It is therefore necessary to measure them to facilitate the process control and optimization to achieve efficient management of industrial processes.

Selvakumar ‡ and Chen-Sheng Yeh* Noninvasive techniques, such as breath tests (urea breath test), blood pressure measurements using a sphygmomanometer, and electrocardiography, were employed by a physician to perform classical diagnosis. The use of state-of-the-art noninvasive therapies at the organ level in modern medicine has gradually become possible. However, cancer treatment demands for spatially and temporally controlled noninvasive therapy at the cell level because nonspecific toxicity often causes complicated side effects. To increase survival in cancer patients further, combination therapy and combination drugs are explored which demand for high specificity to avoid combined drug side effects. We believe that high specificity could be obtained by implementing near-infrared (NIR) light-assisted nanoparticles in photothermal therapy, chemotherapy-, and photodynamic therapy. To refine this therapy and subsequently achieve high efficiency, novel nanomaterials have been designed and modified either to enhance the uptake and drug delivery to the cancer site, or control treatment to administer therapy efficiently. These modifications and developments have been demonstrated to achieve special and temporal control when conducting an in vivo xenograft, because the NIR light effectively penetrated the biological tissue.
