The slag flow rate and heat flux through a combustor wall were measured in a 24 T/D pilot plant of a coal partial combustor, which is one kind of slagging cyclone combustor. Results of computer analysis on the slag behaviour and the heat transfer were compared with good agreement to the test results. The computer model predicted the following characteristics. (1) The slag flow rate showed rapid increase or sudden decrease when combustion conditions were changed. (2) The effects of various factors were evaluated, including the firing rate, combustor stoichiometry, ash content, flux additive, air preheat temperature, enriched oxygen concentration, refractory thickness, cooling-wall temperature and the reactivity of coals.

The Lagrangian model of solid-liquid two phase flow is proposed by combining the Moving Particle Semi-implicit (=MPS) method with the Distinct Element Method (=DEM). The governing equations of two fluid model is discretized by the MPS method, with the model of interparticle collision in solid phase based on the DEM. The relationships of present model with the previous Lagrangian model of a motion of single sediment particle and the non-Newtonian fluid model are discussed. The performance of the present model is investigated by simulating the dropping lump of mud into still water. By comparing the solutions of three models, such as the present model; the two fluid model by the MPS method without the DEM; and the MPS method with the passively moving solids module, the effect of cohesion of mud is reproduced well by the present model.

Numerical approaches of the solid-liquid flows were not established so far. This is because the modeling of free surface and solid phase was difficult, furthermore the calculation cost might become excessive. In the present study, a new method is developed to simulate the solid-liquid flows involving the free surface. In this method, the solid-liquid flows were computed by combining the Discrete Element Method (DEM) and the Moving Particle Semi-implicit (MPS) method. This is called the DEM-MPS method. In the present study, the validation of the DEM-MPS method was performed in a solid-liquid flow involving free surface in a rotating tank. The angle of repose and solid distribution were compared between the simulations and experiments. The simulation results were in good agreement with those obtained by the experiment.

This article presents the political function of the Holy Face of Edessa. one of the most important relics in the Christian world: how it was exploited for imperial legitimacy.<br> In August 944 the Image of Edessa was brought into Constantinople as the fruits of Romanus Is campaign against the Muslims in Syria. The <i>adventus</i> ceremony of the holy image was performed solemnly so that it might miraculously heal the old Emperor of his illness. Romanus I, a usurper, also hoped that the relics would purify his usurpation of the crown from Constantine VII ofthe Macedonian dynasty.<br> In December 944, however, Romanus was forced to abdicate and brought into a monastery. Returning to the throne, Constantine VII also used the holy image as a demonstration of his legitimacy. Under his direction the court intellectuals rewrote the history of the acquisition and the <i>adventus</i> ceremony of the holy image: they insisted that the image celebrated Constantine VII.<br> The most important point to be noted in this article is that the <i>Narratio de imagine Edessena</i>, a history of the Image of Edessa composed at the court of Constantine VII, repeatedly emphasized the images protection of the city of Constantinople. The special emphasis on the Capital City formed a part of the Macedonian dynastic propaganda that the dynasty was related to Constantine the Great, the founder of Constantinople. The Image o f Edessa was hence closely involved in the dynastic politics o f the Byzantine Empire as a <i>palladium</i> of Constantinople.

The expected decrease of the domestic market, combined with limited growth, has caused leading EC operators in Japan to accelerate their expansion of business overseas. Since EC sales channels can overcome geographic limitations, effective utilization of these facilitate store development without committing large investment capital giving opportunity to EC to secure their own target market within the broadening market. Against this background, in recent years, EC related companies in Japan have tried to advance and develop the Chinese market, and results are beginning to appear. What has distinguished those that are successful and those that are not? To clarify the factors, we discuss the development of cross-border EC in the China market. In addition, we propose the features of cross-border e-commerce conceptual model, and examined its usefulness and proposed function.
