Abstract The technical importance of paraffins as phase change materials (PCM) in heat storage systems increases. Knowledge on the thermal conductivity is necessary for design and optimization systems. However, most solely liquid state has been sufficiently investigated. For solid state, precise data are only known a few paraffins, while generalized values available remainder, some which contra...
Solid-liquid phase change thermal diode (SL-PCTD) is potential for rectification, however the unsustainable rectification ratio of SL-PCTD hampers its practical application, demanding a reasonably compatible design. Herein, composed calcium chloride hexahydrate (CaCl2·6H2O) and paraffin wax investigated, where supercooling effect CaCl2·6H2O plays significant role in rectification. In forward di...
For routine EUS-guided sampling of solid masses and lymph nodes (LNs) ESGE recommends 25G or 22G needles (high quality evidence, strong recommendation); fine needle aspiration (FNA) and fine needle biopsy (FNB) needles are equally recommended (high quality evidence, strong recommendation).When the primary aim of sampling is to obtain a core tissue specimen, ESGE suggests using 19G FNA or FNB ne...
Stabilizing Pickering emulsions with metal-organic frameworks (MOFs) is a known way to incorporate them into hierarchically porous materials. Studies generally focus on their final properties and emulsion microstructures are rarely precisely described. Our hypothesis was that characterizing the microstructural rheological of stabilized solely by Al-based MOFs (MIL-96) particles would provide in...
By scanning biological tissues in vivo and in vitro with optical coherence tomography, it is found that liquid paraffin can enhance the percutaneous penetration of glycerol in deep layers of tissue and take synergistically optical clearing effect with glycerol. It is shown from experimental results that 30% - 50% liquid paraffin glycerol solutions have the best enhancement effect. Considering t...
Low-level liquid concentrate wastes including boric acid have been immobilized with paraffin wax using concentrate waste drying system in Korean nuclear power plants since 1995. Small amount of low density polyethylene (LDPE) was added to increase the leaching resistance of the existing paraffin waste form and the influence of LDPE on the leaching behavior of waste form was investigated. It was...
Large samples of tissue and biopsy specimen were taken from a single human liver, homogenized or paraffin-embedded, then analyzed by PIXE. Homogenates, including those of biopsies, proved to be suitable for PIXE-analysis of P, S, Ca, Mn, Fe, Cu, Zn, Se, Rb, Mo, Cd and, to a limited extent, Pb. Paraffin-embedding leads to a distinct elution of K, Rb, Cl and to a lesser elution of P, Zn, Se, Br a...
BACKGROUND AND THE PURPOSE OF THE STUDY Functional constipation is prevalent in children. Recently polyethylene glycol has been introduced as an effective and safe drug to treat chronic constipation. There are only a few clinical trials on comparison of PEG and liquid paraffin in childhood constipation. The purpose of this study was to evaluate clinical efficacy and safety of PEG 3350 solution ...
