In ship construction, line heating is a necessary process for forming plates with complex curvature. The determination of parameters has significant impact on the accuracy and efficiency shipbuilding. However, previous studies this subject only stay at level predicting deformation, which not meet actual processing production requirements. paper, new idea forecasting proposed. Firstly, an Radial...
Oxygen release from metal oxides at high temperatures is relevant to many thermally activated chemical processes, including chemical-looping combustion, solar thermochemical cycles and energetic thermite reactions. In this study, we evaluated the thermal decomposition of nanosized metal oxides under rapid heating (~10(5) K s(-1)) with time-resolved mass spectrometry. We found that the effective...
Hyperthermia is becoming a potent therapeutic method for malignant brain tumors, either alone or in combination with radiation therapy. The heat response of organized tissues includes other factors besides the inherent cellular thermosensitivity, that is, tissue pH, PaO2, and nutrient supply, all of which are largely influenced by the tissue blood flow. In this study, the regional cerebral bloo...
The melting behaviour of d-sucrose, d-glucose and d-fructose was studied. The melting peaks were determined with DSC and the start of decomposition was studied with TG at different rates of heating. In addition, melting points were determined with a melting point apparatus. The samples were identified as d-sucrose, alpha-d-glucopyranose and beta-d-fructopyranose by powder diffraction measuremen...
The use of microwave heating for preparation in organic synthesis has been accepted as an effective technique in synthesis due to the significant advantages over the conventional method. In the present work, microwave heating was applied to the preparation of atrazine (template molecule) magnetic molecularly imprinted polymer (mag-MIP) beads by suspension polymerization. The term of the polymer...
We have developed a steady-state energy balance model of the solar corona, which calculates coronal magnetic field structure and thermodynamics from a photospheric magnetogram. Our method involves a solution of energy and momentum equations along individual coronal loops, allowing for flows, gravity, non-uniform heating, and cross-sectional area variations. The model yields predicted plasma emi...
