Phase change materials (PCMs) are increasingly investigated in the last years as successful many thermal energy storage applications. In building sector, PCMs utilised to improve efficiency by reducing cooling/heating loads and promoting renewable sources, such solar energy. This paper shows recent research works on integrating with envelope for heating purposes. The main PCM categories their c...

Performance was evaluated for a passive solar space heating system utilizing heat pipes to transfer heat through an insulated wall from an absorber outside the building to a storage tank inside the building. The one-directional, thermal diode heat transfer effect of heat pipes make them ideal for passive solar applications. Gains by the heat pipe are not lost during cloud cover or periods of lo...

OBJECTIVE To determine whether local warming of the lower arm and hand facilitates peripheral venous cannulation. DESIGN Single blinded prospective randomised controlled trial and single blinded randomised crossover trial. SETTING Neurosurgical unit and haematology ward of university hospital. PARTICIPANTS 100 neurosurgical patients and 40 patients with leukaemia who required chemotherapy...

Introduction Percutaneous interventions are difficult to perform in closed-bore MRI systems, because access to the target organ is restricted due to the limited space in the magnet. This limitation was overcome with a commercial robotic assistance system (RAS), which can precisely position and orient a medical instrument (e.g., a needle) with a robotic arm. To co-register the robot position in ...

This paper presents a simulation study to reduce heating and cooling energy demand of a school building in Seoul Metropolitan Area, Korea. The aim of this study was to estimate the impact of passive vs. active approaches on energy savings in buildings using EnergyPlus simulation. By controlling lighting, the energy saving of the original school building design was found most significant, and in...
