| 2 | FUZZY MODEL FOR TWO-DIMENSIONAL RIVER WATER QUALITY SIMULATION UNDER SUDDEN POLLUTANTS DISCHARGED显示文摘Based on the fuzziness and impreciseness of water environmental system, the fuzzy arithmetic was used to simulate the fuzzy and imprecise relations in modeling river water quality. By defining the parameters of water quality model as symmetrical triangular fuzzy numbers, a two-dimensional fuzzy water quality model for sudden pollutant discharge is established. From the fuzzy model, the pollutant concentrations, corresponding to the specified confidence level of α, can be obtained by means of the α-cut technique and arithmetic operations of triangular fuzzy numbers. Study results reveal that it is feasible in theory and reliable on calculation applying triangular fuzzy numbers to the simulation of river water quality. | LI Ru-zhong SHIGEKI Masunaga HONG Tian-qiu QIAN Jia-zhong | 2007 | Journal of Hydrodynamics2007，19，4： | 11 |
| 3 | 运用免疫荧光法检测温热对于硼化合物细胞微分布影响显示文摘目的硼中子俘获疗法(BNCT)的有效性主要取决于硼-10元素在肿瘤细胞内的聚集。目前的硼检测手段仅限于分析肿瘤组织中硼的平均浓度,不能准确地评价硼化合物(BPA)在组织中的详细分布。先前研究证实温热处理可以提高放疗疗效,本研究通过免疫荧光法检测温热是否对BPA细胞内的微分布有影响。方法通过免疫荧光法分析硼化合物在肿瘤细胞中的分布以及温热对BPA分布的影响。在体外对人肺癌细胞株A549和人头颈部鳞状细胞癌细胞株SAS进行培养,并且加入BPA共培养1h。另外,A549细胞经温热处理1h后,利用抗BPA抗体通过免疫荧光法进行检测。免疫荧光强度通过图像分析软件进行分析。结果检测发现BPA主要聚集于细胞核周围,BPA免疫荧光的强度随着培养基中BPA浓度的增加而增强。尽管在26μg/ml浓度和13μg/ml浓度时,细胞免疫荧光的平均强度相近,但直方图分析发现26μg/ml时细胞主要向高荧光强度区域移动。经温热处理后,BPA在细胞中的分布没有明显增加。结论本研究利用免疫荧光法对BPA在细胞内的分布进行了分析,以上结果暗示温热对肿瘤细胞硼摄取的影响可能主要需要通过改善肿瘤循环、增加肿瘤内BPA的输送来实现。 | 刘勇 Kashino Genro 陈一瑋 Masunaga Shin-ichiro Suzuki Minoru Kinashi Yuko Kirihata Mitsunori Ono Koji | 2012 | 中华临床医师杂志(电子版)2012，6，10： | 3 |
| 4 | Derivation of salt content in salinized soil from hyperspectral reflectance data: A case study at Minqin Oasis, Northwest China显示文摘Soil salinization is a serious ecological and environmental problem because it adversely affects sustainable development worldwide, especially in arid and semi-arid regions. It is crucial and urgent that advanced technologies are used to efficiently and accurately assess the status of salinization processes. Case studies to determine the relations between particular types of salinization and their spectral reflectances are essential because of the distinctive characteristics of the reflectance spectra of particular salts. During April 2015 we collected surface soil samples(0–10 cm depth) at 64 field sites in the downstream area of Minqin Oasis in Northwest China, an area that is undergoing serious salinization. We developed a linear model for determination of salt content in soil from hyperspectral data as follows. First, we undertook chemical analysis of the soil samples to determine their soluble salt contents. We then measured the reflectance spectra of the soil samples, which we post-processed using a continuum-removed reflectance algorithm to enhance the absorption features and better discriminate subtle differences in spectral features. We applied a normalized difference salinity index to the continuum-removed hyperspectral data to obtain all possible waveband pairs. Correlation of the indices obtained for all of the waveband pairs with the wavebands corresponding to measured soil salinities showed that two wavebands centred at wavelengths of 1358 and 2382 nm had the highest sensitivity to salinity. We then applied the linear regression modelling to the data from half of the soil samples to develop a soil salinity index for the relationships between wavebands and laboratory measured soluble salt content. We used the hyperspectral data from the remaining samples to validate the model. The salt content in soil from Minqin Oasis were well produced by the model. Our results indicate that wavelengths at 1358 and 2382 nm are the optimal wavebands for monitoring the concentrations of chlorine and sulphate compounds, the predominant salts at Minqin Oasis. Our modelling provides a reference for future case studies on the use of hyperspectral data for predictive quantitative estimation of salt content in soils in arid regions. Further research is warranted on the application of this method to remotely sensed hyperspectral data to investigate its potential use for large-scale mapping of the extent and severity of soil salinity. | QIAN Tana Atsushi TSUNEKAWA PENG Fei Tsugiyuki MASUNAGA WANG Tao LI Rui | 2019 | Journal of Arid Land2019，11，1： | 3 |
| 5 | Soil Development and Fertility Characteristics of Inland Valleys in the Rain Forest Zone of Nigeria: Mineralogical Composition and Particle-Size Distribution显示文摘The particle-size distribution and mineralogical composition of the clay (< 2 μm) and fine-sand (0.25-0.10 mm) fractions in soils of two inland valleys in Abakaliki and Bende, Southeast Nigeria, were investigated to provide basic information on soil-forming processes and agricultural potentials. These soils were silty or clayey, deriving from Cretaceous or Tertiary shale materials. The particle-size distribution and its computation on a clay-free basis revealed relatively remarkable lithologic breaks in a couple of pedons. The effect of lithologic discontinuities on soil mineralogical composition was not, however, conspicuous. Petrographic investigation revealed that quartz predominantly comprised the fine-sand fraction in the soils at both study sites. Nevertheless, the clay mineralogical composition of the soils was a mixture of kaolinite, irregularly interstratified smectite-illite intergrades (S/I), hydroxyl-Al interlayered 2:1 type clays (HICs), vermiculite, smectite, halloysite and illite along with fine-sized quartz in Abakaliki. The soils of Bende predominantly contained smectite, which was partially interlayered with hydroxyl-Al and kaolinite. It is suggested that seasonal floodwater has slowed the disintegration of weatherable clay minerals inherited from the shale, while quartz originating from the sandstone is predominant in the fine-sand fraction. Additionally, a possible soil-forming process observed at the both study sites was ferrolysis, which was indicated by a clear decreasing pattern of HICs downward in the soil profiles. The entry of S/I and vertical distribution patterns for a couple of clay minerals in the pedon suggested that the soils in Abakaliki have developed under the significant influence of aeolian dust delivered by the Harmattan. The findings might describe a site-specific deposition pattern of Harmattan dusts as well as hydromorphic soil-forming processes in the wetlands of the inland valleys. | S. S. ABE G. O. OYEDIRAN T.
