以苯乙烯乳液聚合合成种子, 再在种子外生成苯乙烯与甲基丙烯酸 3 三甲氧基硅丙酯 (MPS) 的共聚物,利用MPS中硅氧烷基的水解缩合反应, 形成交联的壳, 得到有机无机杂化型核壳乳胶粒. 然后用溶剂将聚苯乙烯模板溶解, 可得到空心微胶囊. 通过透射电镜 (TEM) 和动态光散射粒径仪 (DLS) 观测乳胶粒及微胶囊的形态. 并研究了乳化剂种类、介质 pH值、MPS用量和加入方式对粒径、粒子数和体系稳定性的影响. 发现非离子型乳化剂、酸性或碱性介质、MPS用量过多均促进乳胶粒子数减少, 减弱了乳液稳定性. 而采取连续滴加MPS的方法则可提高乳液的稳定性, 且粒径可控.

Investigating the dynamics and distribution of soil phosphorus(P) fractions can provide a basis for enhancing P utilization by crops. Four treatments from a 29-year long-term experiment in black soil with maize cropping were involved in this study: no fertilizer(CK), inorganic nitrogen and potassium(NK), inorganic nitrogen, phosphorus, and potassium(NPK), and NPK plus manure(NPKM). We analyzed soil P fractions in different soil layers using a modified Hedley sequential method. The long-term NPKM treatment significantly increased total P by 0.6–1.6 times in the different soil layers. The Olsen-P concentration far exceeded the environmental threshold for soil Olsen-P(50.6 mg kg) in the NPKM treatment in the 0–60 cm soil profile. Moreover, the concentrations and proportion of labile and partially labile inorganic P(Pi) fractions(i.e., Na HCO-extracted Pi, Na OH-extracted Pi, and dilute HClextracted Pi) to the sum of all P fractions(Pt) in the 0–60 cm soil profile were higher in the NPKM treatment than in the NPK treatment, indicating that manure could promote the transformation of non-labile into more labile forms of P in soil, possibly by manure reducing P fixation by soil particles. Soil organic matter, Mehlich-3 extractable iron(Fe), and organic-bound aluminum were increased by fertilization, and were the main factors influencing the differences in the P fractions in the 0–20 cm soil layer. Soil mineral components, i.e., free Fe oxide and Ca CO, were the main factors influencing the P fractions in the subsoil. The soil P transformation process varied with soil layer and fertilization. Application of manure fertilizer can increase the labile(Olsen) P concentrations of the various soil layers, and thus should reduce the mineral P fertilizer requirement for crop growth and reduce potential environmental damage.

We report the case of a 57-year-old man who was diagnosed with a large unresectable cholangiocarcinoma associated with 2 satellite nodules and without clear margins with the right hepatic vein. Despite 4 cycles of GEMOX (stopped due to a hypertransaminasemia believed to be due to gemcitabine) and 4 cycles of FOLFIRINOX, the tumor remained stable and continued to be considered unresectable. Radioembolization (resin microspheres, SIRS-spheres®) targeting the left liver (474 MBq) and segment IV (440 MBq) was performed. This injection was very well tolerated, and 4 more cycles of FOLFIRINOX were given while waiting for radioembolization efficacy. On computed tomography scan, a partial response was observed; the tumor was far less hypervascularized, and a margin was observed between the tumor and the right hepatic vein. A left hepatectomy enlarged to segment VIII was performed. On pathological exam, most of the tumor was acellular, with dense fibrosis around visible microspheres. Viable cells were observed only at a distance from beads. Radioembolization can be useful in the treatment of cholangiocarcinoma, allowing in some cases a secondary resection.

Real-time track reconstruction in high-energy physics experiments at colliders running at high luminosity is very challenging for trigger systems. To perform pattern recognition and track fitting, artificial retina or Hough transformation algorithms have been introduced to the field typically implemented on state-of-the-art field programmable gate array(FPGA) devices. In this paper, we report on two FPGA implementations of the retina algorithm: one using a mixed Floating-Point core and the other using Fixed-Point and Look-Up Table, and detailed measurements of the retina performance are investigated and compared. So far, the retina has mainly been used in a detector configuration comprising parallel planes, and the goal of our work is to study the hardware implementation of the retina algorithm and estimate the possibility of using such a method in a real experiment.

Assessing spatial variability and mapping of soil properties constitute important prerequisites for soil and crop management in agricultural areas. To explore the relationship between soil spatial variability and land management, 256 samples were randomly collected at two depths (surface layer 0–20 cm and subsurface layer 20–40 cm) under different land use types and soil parent materials in Yujiang County, Jiangxi Province, a red soil region of China. The pH, soil organic matter (SOM), total nitrogen (TN), cation exchange capacity (CEC), and base saturation (BS) of the soil samples were examined and mapped. The results indicated that soils in Yujiang were acidified, with an average pH of 4.87 (4.03–6.46) in the surface layer and 4.99 (4.03–6.24) in the subsurface layer. SOM and TN were significantly higher in the surface layer (27.6 and 1.50 g kg–1, respectively) than in the subsurface layer (12.1 and 0.70 g kg–1, respectively), while both CEC and BS were low (9.0 and 8.0 cmol kg–1, 29 and 38% for surface and subsurface layers, respectively). Paddy soil had higher pH (mean 4.99) than upland and forest soils, while soil derived from river alluvial deposits (RAD) had higher pH (mean 5.05) than the other three parent materials in both layers. Geostatistical analysis revealed that the best fit models were exponential for pH and TN, and spherical for BS in both layers, while spherical and Gaussian were the best fitted for SOM and CEC in the surface and subsurface layers. Spatial dependency varied from weak to strong for the different soil properties in both soil layers. The maps produced by selecting the best predictive variables showed that SOM, TN, and CEC had moderate levels in most parts of the study area. This study highlights the importance of site-specific agricultural management and suggests guidelines for appropriate land management decisions.

在三维地震资料叠前偏移中,平面波偏移的成像效果可以等价于共炮点偏移,但计算效率却能成倍提高。此外,保真振幅偏移可以得到地下反射层的相对强度,获得品质更好的地下结构图像,为储层分析提供定量信息。基于这种考虑,针对平面波的保真振幅偏移进行了系统的研究。引人Maslov理论,利用τ-ρ变换将数据从空间(s,r,t)分别变换到(P^s,r,τ)和(s,p^r,τ)及(p^s,p^r,τ)空间中,并将其结合到Born反演中,推导出了相空间偏移算子振幅的高频渐近解。基于Marmousi复杂地质模型的模拟计算结果表明,平面波的保真振幅偏移在合理的计算量条件下可以得到高品质的地下结构图像。
