The present work is investigated the in-situ monitoring of local corrosion process of scratched epoxy coated carbon steel in saturated Ca(OH)2 with and without 3% NaCl using SECM and correlated with EIS. The results obtained from EIS analysis showed that the corrosion resistance of scratched epoxy coated carbon steel decreases in Cl- containing solution as the increase in wet/ dry corrosion cycles. This was indicated by decrease in film resistance (Rf) and charge transfer resistance (Rct), while the coated steel maintain the resistance values in saturated Ca(OH)2, most of which recovered after drying. The corrosion process was monitored using SECM by setting the tip potential at -0.70 V vs Ag/AgCl, where the consumption of dissolved oxygen occurred at the surface of test sample. The consumption of dissolved oxygen current (I’oxy-c) values was increased during the immersion in a solution with 3% NaCl. However, in wet/dry corrosion cycles, I’oxy-c was decreased due to the coverage of hydroxides/oxides at scratch area which suppressed the consumption of dissolved O2. It was found that the continuous decrease in corrosion was mainly attributed to continuous formation of corrosion products at anodic spots.

Background: Bevacizumab-based chemotherapy has been shown to extend progression-free survival (PFS) of lung cancer, but its effect on overall survival (OS) remains unclear. However, bevacizumab beyond disease progression (BBP) significantly improved OS in patients with metastatic colorectal cancer. Methods: Therefore, we retrospectively analysed 22 patients with non-small cell lung cancer (NSCLC) who were treated with docetaxel plus BBP at the Department of Thoracic Oncology, Kansai Medical University Hirakata Hospital, between November 2009 and March 2013. Results: The response rate was 31.8% and the disease control rate was 86.4%. The median PFS was 4.5 months (95% confidence interval [CI], 2.5 - 8.7 months) and the median OS was 17.2 months (95% CI, 8.5 - 25.9 months). Grade 3 and 4 adverse events included leukocytopenia (68.2%), neutropenia (77.3%), fatigue (9.1%), proteinuria (9.1%), febrile neutropenia (4.5%), anemia (4.5%), and anorexia (4.5%). Conclusion: Docetaxel plus BBP was found to be generally well tolerated and effective.

In late years the use of UAV which is suitable for the observation activities in a dangerous area is pushed forw ard.R otary wing type UAV which can perform vertical takeoff and landing and hovering is used. We propose a compact U AV called SW U M which is without tail rotor. We adopt " stator wing" as an anti- torque compensation mechanism instead of a tail ***,the attitude control test around yaw axis was performed using the SW UM prototype on a free rotational table. It was confirmed that the attitude of the vehicle around yaw axis by stator wings was controlled well. We studied a control method for translational motion of this vehicle. The horizontal translational motion will be achieved by tilting the body fone of stator *** created the mathematical model of the kinetics of this vehicle,and are performed analysis by the computer simulation.

Accurate evaluation of unsaturated soil properties is critical for the design of geotechnical and geo-environmental structures such as road pavements, foundations, and earth dams. Water retention activity in soils which is used to predict the stability or seepage problems in the ground is one of the key features in unsaturated soil mechanics. Thus, many experimental works have reported on the unsaturated soil properties, and the soil-water characteristic curve (SWCC) test has contributed significantly to the interpretation of matric suction. Since traditional instruments cannot apply stress in SWCC tests, some researchers have developed suction controlled triaxial apparatus, by which SWCC tests are performed under different stress states. Determination of SWCCs under stress conditions similar to those in the field is key for interpretation of the hydro-mechanical behavior of unsaturated soils. This study conducted SWCC tests of unsaturated silt soil in low matric suction ranges under both drying and wetting conditions. The SWCCs were measured under one-dimensional and isotropic confining stresses ranging from 50 to 450 kPa. The micro porous membrane method was used instead of high air entry ceramic disk for controlling relatively low matric suction. The range of matric suction controlled was from 0 to 20 kPa. The study revealed that the measured SWCC in low matric suction ranges seems to be affected by the influence of stress conditions. Isotropic confining stress caused the void structure of the specimen to become dense and consequently, soil moisture flow movement also decreased. The water retention activity was obviously high, and the point regard to air entry value was larger. The study further suggests that the current methods adopted for estimating unsaturated soil properties require further development to take into account the effect of different stress conditions.

A selective ensemble mean technique for tropical cyclone(TC)track forecasts,which excludes from the ensemble those models that have large position errors at short lead times,was applied to a set of TC track forecasts produced by 11 operational global deterministic *** position errors of the resulting selective ensemble mean TC track forecasts were verifi ed for 91 TCs in the western North Pacifi c from 2010 to 2013 that reached an intensity classifi cation of'tropical storm'or *** TC position errors of the selective ensemble mean were smaller than those of a simple 11-member ensemble mean by 14.4%,7.4%and 4.7%at forecast times of24,48 and 72 hours,***,the errors were larger than those of the best single-model-based deterministic forecasts,which were ECMWF *** correlation between TC position errors at short and long lead times was weak,which partially explains why the selective ensemble mean technique in this study had lesser skill than ECMWF *** operational forecasting,simple ensemble mean forecasts by ECMWF and NCEP generally provide the best forecast performance for verifi cation samples from 2010 to 2013.

Cost reduction in electric power generation is a major management concern, and it is therefore necessary to reduce maintenance expenses while upholding plant reliability. A maintenance optimization system 'FREEDOM', which uses RBM technique, DCF (discounted cash flow) and NPV (net present value) calculation functions, has been newly developed. This system probabilistically evaluates the lifetime of boiler and turbine and quantitatively calculates the risk defined as the cumulative probability of failure multiplied by the consequence of failure. Economically optimized timing of inspection and alternative countermeasure such as repair and replacement are then recommended. This system has already been applied to seven plants in Japan, and its effectiveness has been confirmed.

当冲击试验电压高时,冲击试验电压的波形叠加过冲和振荡。这是由于冲击试验回路的残余电感、被试设备的大杂散电容或二者共同作用产生的。文章用4次微分方程式对振荡冲击试验的等值回路进行了分析,结果表明,波形可分为非振荡波头、振荡波头、非极性反转波尾、非振荡的极性反转波尾和振荡极性反转波尾5个部分。非振荡的极性反转波尾和振荡极性反转波尾的产生原理是不同的。波形的高频分量定义为振荡波形,非振荡波形是不含振荡波形成份的波形。文章的研究结果是后者的产生原因和等值电阻、等值电感的关系以及4次方程的根有关。文章给出了它们之间的关系。

Objective The changes in serum adipokines and cytokines related to oxidative stress were examined during 3 months ‘Off to On’ and ‘On to Off’ periods using negatively charged particle-dominant indoor air conditions（NCPDIAC）.Methods Seven volunteers participated in the study,which included ‘OFF to 3 months ON’ periods（ON trials） for a total of 16 times,and ‘ON to 3 months OFF’（OFF trials） periods for a total of 13 *** With the exception of one case,serum amyloid A（SAA） levels decreased significantly during the ON *** Considering that SAA is an acute phase reactive protein such as C reactive protein（CRP）,this observed decrease might indicate the prevention of cardiovascular and atherosclerotic changes,since an increase in high-sensitive CRP is associated with the subsequent detection of these events.
