Various process residues represent a kind of biomass resource already concentrated but containing water as much as 60 wt.%. These materials are generally treated as waste or simply combusted directly to generate heat. Recently, we attempted to convert them into middle caloric gas to substitute for natural gas, as a chemical or a high-rank gaseous fuel for advanced combustion utilities. Such conversion is implemented through dual fluidized bed gasification （DFBG）. Concerning the high water content of the fuels, DFBG was suggested to accomplish either with high-efficiency fuel drying in advance or direct decoupling of fuel drying/pyrolysis from char gasification and tar/hydrocarbon reforming. Along with fuel drying, calcium-based catalyst can be impregnated into the fuel, without much additional cost, to increase the fuel＇s gasification reactivity and to reduce tar formation. This article reports the Ca impregnation method and its resulting effects on gasification reactivity and tar suppression ability. Meanwhile, the principle of directly gasifying wet fuel with decoupled dual fluidized bed gasification （D-DFBG） is also highlighted.

AIM： To determine the relationship between the subfoveal choroidal thickness（CT） and intraocular pressure（IOP） following idiopathic epiretinal membrane（ERM） ***： Retrospective observational case series of patients who had undergone 23-gauge vitrectomy for an ERM. The measurements of CT and IOP were done at the baseline and 1 d, 1 wk, 1, 3, 6, and 12 mo after the ***： Forty-four eyes of 43 patients with a mean age of 69.8±9.5 y were studied. The CT was 200.8±86.3 μm at the baseline, 210.1±83.5 μm at 1 d, 213.2±85.4 μm at 1 wk, 203.1±84.0 μm at 1 mo, 197.5±85.5 μm at 3 mo, 197.7±84.0 μm at 6 mo, and 191.2±86.8 μm at 12 mo after surgery. The CT on day 1 and week 1 after the surgery was significantly thicker than that at the baseline CT（P=0.0023 and P〈0.0001）. The CT at 12 mo after surgery was significantly thinner than the baseline（P=0.0062）. The IOP on day 1 and week 1 were significantly lower than the baseline（P〈0.0001 and P=0.0042）. The IOP at 1, 3, 6, and 12 mo after surgery were significantly higher than the baseline IOP（P=0.0087, P=0.0023, P〈0.00051, and P〈0.0001）. The rates of changes in the CT between baseline and day 1 and week 1 were significantly and negatively correlated with the rates of change in the IOP（P〈0.0001 and P=0.046）. In the group with the IOP change rate of-30% or less at 1 d postoperatively, the change rate of CT was-21.1% to 31.2%（9.8%±12.4%） and in the group of-29% or more, it was-8.9% to 28.0%（2.6%±8.9%）. The change rate of CT in the group with the IOP change rate of-30% or less was significantly higher than the group of-29% or more（P=0.016）.CONCLUSION： CT increases soon after the ERM surgery which is probably due to the transient hypotony, showing that IOP may be a significant confounding factor for CT.

This article is to offer a concise review on the use of cytoreductive surgery （CRS） plus intraperitoneal hyperthermic chemotherapy （IPHC） for the treatment of peritoneal carcinomatosis （PC）. Traditionally, PC was treated with systemic chemotherapy alone with very poor response and a median survival of less than 6 too. With the establishment of several phase Ⅱ studies, a new trend has been developed toward the use of CRS plus IPHC as a standard method for treating selected patients with PC, in whom sufficient cytoreduction could be achieved. In spite of the need for more high quality phase Ⅲ studies, there is now a consensus among many surgical oncology experts throughout the world about the use of this new treatment strategy as standard care for colorectal cancer patients with PC. This review summarizes the current status and possible progress in future.

The effects of tube bank configuration on forces and heat transfer were investigated for both two-dimensional and three-dimensional gas fluidized beds. Effective dynamic forces and heat transfer coefficients were measured for several tube bank configurations, and it was found that the average forces are smaller than for a single tube. The heat transfer coefficient can be increased by providing sufficient space for particles to descend around both sides of the tube bank. The results provide useful guidelines for optimizing the configuration of tube banks to achieve high heat transfer coefficients while reducing tube erosion due to dynamic forces.

Radio-photoluminescence （RPL） is a phenomenon seen in luminescent materials in which the appearance of new photolu- minescence （PL） emission is induced by an incident ionizing radiation such as X-rays; and the signal is stable even after the irradia- tion and during the PL measurement. Since the induced PL intensity is proportional to the irradiation dose, the RPL can be used in ra- diation measurements. The distinct advantage of RPL over the conventional thermally- or photo-stimulated luminescence （abbrevi- ated as TSL or PSL） dosimeters is the stability of response signal. With an RPL detector, it allows us to readout the signal multiple time without signal fading. In this work, we discovered that CsBr：Sm showed an RPL phenomenon by X-ray irradiation, and we characterized this new material as an RPL detector. While the sample showed PL emissions mainly in the visible range, after an X-ray irradiation additional emissions could be observed in the red to near-infrared range around 650-850 nm and 900-1000 nm and longer. The RPL response was fairly stable overall, but very interestingly the 650-850 nm signal slightly increased while the 900-1000 nm decreased during PL readout. The dynamic range was confirmed over 1-104 mGy with linear response.
