The effect of Ru on microstructure stability and stress rupture properties of a Ni3Al single-crystal alloy was investigated. The experimental results showed that the addition of 2%Ru(mass fraction) improved the microstructure stability due to the restraint of harmful Y-NiMo phase formation during the thermal exposure at the high temperature above 1 000℃.And the reason may be that the addition of Ru increased the degree of Mo supersaturation in bothγandγ’ phases,and hence suppressed the precipitation of Y-NiMo *** results of stress rupture tests under the testing condition of 1100℃,120 MPa showed that the addition of 2% Ru in the alloy improved the stress rupture lives significantly for thermal exposed *** improvement of the stress rupture properties may be attributed to the restraint of Y-NiMo phase precipitation and growth by the addition of the proper amount Ru.

A field experiment was conducted at the Shenyang Experimental Station ofEcology, Chinese Academy of Sciences, to study the effects of soil management practices on water useand rice (Oryza sativa L.) yield in an aquic brown soil during 2001 and 2002. A completely randomexperimental design with three replications was employed, having four soil management practices astreatments, namely: an undisturbed plow layer (CK), a thin plastic film (TN), a thick plastic film(TI) and subsoil compacting (CP). Results indicated no significant differences among all treatmentsfor rice biomass and grain yields. Also, water consumption was about the same for treatments TN andCK, however the treatments TI and CP were much lower with more than 45% and 40% of the irrigationwater in the treatments TI and CP, respectively, saved each year compared to CK. Therefore, wateruse efficiency was higher in the treatments TI and CP. These results will provide a scientific basisfor the water-saving rice cultivation.

NO气体是大气中的一种重要污染物,如何将其转化为对环境无毒无害的物质近年来引起人们的广泛关注。我们采用密度泛函理论,研究NO在TiO2表面的催化反应。通过我们的研究发现,NO在TiO2表面存在两种稳定的吸附方式。同时,我们的研究也发现存在三条能量上可行的路径可以把NO催化转化为对环境无毒无害的NH3分子和H2O分子。值得注意的是TiO2表面OH的覆盖率对反应有很大的影响。

Vortex transmutation utilizes a periodic system, which not only enables the alteration of the topological charge(TC) of unstable input vortices but also facilitates their transformation into stable structures. This approach is crucial for investigating the characteristics of vortices in various wave systems. Here, we achieve acoustic vortex TC transmutation by employing a welldesigned dual-structured plate external system(DPES). The interactions between the acoustic vortex and the finite-order discrete rotational symmetry lead to the transformation of its topological charge when complete rotational symmetry is broken to Nthorder discrete symmetry. Our results experimentally demonstrate the acoustic vortex TC transmutation based on passive artificial structures, enabling numerous applications in particle manipulation and information multiplexing as well as advancing our understanding and control over free-space acoustic vortices.

AIM: To investigate transarterial chemoembolization(TACE) with hepatic infusion of oxaliplatin and 5-fluorouracil and Lipiodol chemoembolization in large hepatocellular carcinoma(HCC).METHODS: In this retrospective study, 132 patients with unresectable HCCs larger than 10 cm were treated with hepatic infusion of oxaliplatin and 5-fluorouracil followed by Lipiodol chemoembolization. The primary endpoint was overall survival(OS). Sixteen-week disease-control rate, time to progression(TTP), and major complications were also studied. Univariate and multivariate analyses were performed to identify prognostic factors affecting OS and ***: A total of 319 procedures were performed in the 132 patients. Eleven(8.3%) patients received radical resection following TACE treatment(median time to initial TACE 4.3 ± 2.3 mo). The median OS and TTP were 10.3 and 3.0 mo respectively, with a 50.0% 16-wk disease-control rate. Major complications were encountered in 6.0%(8/132) of patients following TACE and included serious jaundice in 1.5%(2/132) patients, aleukia in 1.5%(2/132), and hepatic failure in 3.0%(4/132). One patient died within one month due to serious hepatic failure and severe sepsis after receiving the second TACE. The risk factor associated with TTP was baseline alpha-fetoprotein level, and vascular invasion was an independent factor related to ***: Hepatic infusion of oxaliplatin and 5-fluorouracil followed by lipiodolized-chemoembolization is a safe and promising treatment for patients with HCCs larger than 10 cm in diameter.
