The Computerised Tomography and Magnetic Resonance Imaging (CT/MRI) technologies have been playing important roles in medical diagnosis and treatments. With the advancements of computer graphics, design and manufacturing technologies in recent decades, medical imaging data such as CT/MRI has been used for personalized design and development of medi...

Cranial defects which are caused by bone tumors or traffic accidents are treated by cranioplasty techniques. Cranioplasty implants are required to protect the underlying brain, correct major aesthetic deformities, or both. With the rapid development of computer graphics, medical image processing (MIP) and manufacturing technologies in recent decade...

A project to research the application of nondestructive assay (NDA) to spent fuel assemblies is underway. The research team comprises the European Atomic Energy Community (EURATOM), embodied by the European Commission, DG Energy, Directorate EURATOM Safeguards; the Swedish Nuclear Fuel and Waste Management Company (SKB); two universities; and sever...

The purpose of the Next Generation Safeguards Initiative (NGSI)-Spent Fuel (SF) project is to strengthen the technical toolkit of safeguards inspectors and/or other interested parties. The NGSI-SF team is working to achieve the following technical goals more easily and efficiently than in the past using nondestructive assay measurements of spent fu...

This research focused on the analysis of a set of stationary passive gamma measurements taken on the spent nuclear fuel assemblies from a boiling water reactor (BWR) using pulse height analysis data acquisition. The measurements were performed on 25 different BWR assemblies in 2014 at Sweden's Central Interim Storage Facility for Spent Nuclear Fuel...

Surprisingly, lung disease is still one of the leading causes of deaths in the developed countries, including UK. According to the UK National Health Service (NHS), Chronic Obstructive Pulmonary Disease (COPD) is the fifth biggest killer disease in the UK, killing approximately 25,000 people a year. This problem is even worse in developing countrie...

The Swedish Nuclear Fuel and Waste Management Company (SKB), European Atomic Energy Community (Euratom), two universities and several U.S. Department of Energy Laboratories have joined in a collaborative research effort to determine the capability of non-destructive assay (NDA) techniques for spent fuel to meet the combined needs of the safeguards...

To quantify interfraction motion in patients with intact cervical cancer and assess implications for clinical target volume (CTV) coverage and required planning margins. We analyzed 10 patients undergoing external beam radiotherapy using online cone beam computed tomography (CBCT) before each fraction. CTVs were contoured on the planning CT and on...

Purpose: To derive an appropriate CTV‐to‐PTV margin that will ensure delivery of 100% of the prescribed dose to 95% (on average) of daily CTV's during a treatment course. Method and Materials: Daily CBCTimages are taken for setup of Stage I–IVa cervical cancer patients at our institution. Daily CTV contours drawn on these images take into account t...

This paper presents a field case study describing how 3-D geological data are used in reservoir simulation to improve performance forecast and help optimize the development of the Serang Field, East Kalimantan, Indonesia. The Serang field consists of complex stacked fluvial and deltaic channel sands under a large gas cap and over a strong aquifer....

Exploitation of ultra-thin oil columns under gas cap and water support is challenging since both gas and water coning can seriously curtail oil recovery. Horizontal wells have shown to alleviate some of this problem as they allow for less drawdown and hence reduce coning for better recovery efficiency. Although the industry has shown horizontal dri...

This paper presents a case study to look back on the performance of over 50 horizontal wells recently drilled in three different fields in the Mahakam Delta, offshore East Kalimantan, Indonesia. The common application of these horizontal wells is to produce thin oil bands sandwiched between gas cap and bottom/edge aquifer. The objective of the stud...

Variables effecting removal of neuroblastoma cells from bone marrow using monoclonal antibodies and magnetic immunobeads were studied. Human neuroblastoma cell lines were labeled with the supravital DNA stain Hoechst 33342, seeded into normal bone marrow, incubated with monoclonal antibodies recognizing neuroblastoma cell surface antigens (HSAN 1.2...
