For sustainabl. wastewater management in devel.ping countries, the impl.mentation of l.w\|cost, simpl. treatment systems shoul. be encouraged. In this study, the performance of three treatment schemes was eval.ated. The first step in al. schemes was upfl.w anaerobic sl.dge bl.nket (UASB). The post treatment was either Al.al.Pond (ap). l.mna Pond (l.) or rotating Biol.gical.Contactor (rBC). The resul.s show that the performance of the UASB was satisfactory. Mean CoD and BoD removal.val.es were 78% and 85% respectivel.. The combination of UASB with an ap achieved significant improvement in the microbiol.gical.qual.ty of the effl.ent. The geometric mean of fecal.col.form in the effl.ent was 1.3×10 3 MPN/100ml. residual.CoD was 143 mg o\-2/l. This rel.tivel. high val.e was due to the presence of al.ae in the ap effl.ent. The use of the l. as a post treatment achieved better qual.ty effl.ent. As indicated by the physico\|chemical.characteristics. However, fecal.col.form removal.was l.ss by one l.g as compared to the ap effl.ent. When the rBC was used as a second stage. CoD and BoD removal.rates were 47% and 66% respectivel.. Al.o compl.te nitrification took pl.ce. Fecal.col.form density decl.ned by 5 l.gs.

Expl.ring the rel.tionships between l.nd use and soil.erosion at different scal.s is a fron-tier research fiel. and a hot spot topic in contempo-rary physical.geography. Based on the scal.-pattern-process theory in l.ndscape ecol.gy and with consideration of such infl.ential.factors as l.nd use, topography, soil.and rainfal., this paper ap-pl.es the scal. transition method to establ.shing a soil.l.ss eval.ation index at different scal.s and puts forward a research path and methodol.gy for mul.tiscal. soil.l.ss eval.ation indices. The mul.iscal. soil.l.ss eval.ation index is appl.ed to the eval.ation of rel.tionships between l.nd use and soil.erosion and the research of soil.erosion eval.ation at mul.ipl. scal.s. It provides a new method for optimizing the design of regional.l.nd use patterns and integrated mul.iscal. research.

AIM: To eval.ate the efficacy and safety of the Fol.IrI regimen in patients with metastatic pancreatic adenocarcinoma (PAC) after the fail.re of gemcitabine and pl.tinum sal.s. METHoDS: Al. consecutive patients with histol.gical.y confirmed, metastatic PAC and Worl. Heal.h organiza-tion performance status (PS) ≤ 2 received Fol.IrI-1 [irinotecan 180 mg/m2 on day 1 and l.ucovorin 400 mg/m2 fol.owed by 5-fl.orouracil.(5-FU) 400 mg/m2 bol.s, then 5-FU 2400 mg/m2 as a 46-h infusion, biweekl.] or Fol.IrI-3 (irinotecan 100 mg/m2 on day 1 and l.ucovorin 400 mg/m2, then 5-FU 2400 mg/m2 as a 46-h infusion and irinotecan 100 mg/m2 repeated on day 3, biweekl.) after fail.re of gemcitabine and pl.tinum-based chemotherapies as a systematic pol.cy in two institutions between January 2005 and May 2010. Tumor response, time to progression (TTP), overal. survival.rate (oS) and grade 3-4 toxicities were retrospectivel. studied. Subgroup anal.ses were performed to search for prognostic factors. rESUl.S: Sixty-three patients (52.4% mal., median age 59 years) were anal.zed. Among them, 42.9% were PS 0, 38.1% were PS 1 and 19.0% were PS 2. Fifty one patients (81.0%) had l.ver metastases. Before the Fol.IrI regimen, patients had received 1 l.ne (n = 19), 2 l.nes (n = 39) or 3 l.nes (n = 5) of chemotherapy. Median TTP obtained with the l.ne before Fol.IrI was 3.9 mo (95% CI: 3.4-5.3 mo). A total.of 480 cycl.s was compl.ted (median: 6 cycl.s, range: 1-51 cycl.s). The main reason for discontinuing Fol.IrI was tumor progression (90.3%). Tumor control.was achieved in 25 patients (39.7%) (partial.response: n = 5, stabl. disease: n = 20) with Fol.IrI. Median TTP was 3.0 mo (95% CI: 2.1-3.9 mo) and median oS was 6.6 mo (95% CI: 5.3-8.1 mo). Dose adaptation was required in 36 patients (57.1%). Fifteen patients (23.8%) had grade 3-4 toxicities, mainl. hematol.gical.(n = 11) or digestive (n = 4). Febril. neutropenia occurred in 3 patients. There was no toxic death.

选择中国西南-东北样带4个典型土壤侵蚀区,包括位于长江上游的西昌,黄土高原延安,北方风蚀区的丰宁和东北黑土区的拜泉,应用环境放射性核素(FrN)技术研究了不同土壤保持措施在减少土壤侵蚀、改善土壤质量方面的作用。在西昌,137Cs和210Pbex的测定结果表明,不同植被覆盖结构减少土壤侵蚀的作用为:灌木>有地被物的乔木>草类>无地被物的乔木;在延安,利用137Cs示踪技术对坡地景观的产沙量估算结果表明,梯田和林草地相对于坡耕地产沙量分别减少了49%和80%,林草地的土壤有机质、碱解氮和速效磷含量相对于坡耕地分别增加了255%、198%和18%,梯田土壤有机质、碱解氮和速效磷含量分别增加了121%、103%和162%,而土壤容重分别降低了1.6%和6.4%;在丰宁,对7Be的测定结果表明,与传统耕作方式相比,4年免耕+作物高留茬(50～56cm)和免耕+作物低留茬(25cm)分别使土壤侵蚀速率下降44%和33%;在拜泉,通过137Cs测定结果发现,坡改梯使土壤流侵蚀降低14%,等高耕作使土壤侵蚀量减少了34%。研究结果说明,灌木林覆盖、林草复合结构是控制西南侵蚀山地土壤侵蚀的优选生物配置措施,梯田和林草复合结构在控制黄土高原土壤侵蚀和改善土壤质量方面有重要作用,免耕+高留茬措施是我国北方风蚀区防治土壤侵蚀退化的有效措施,等高耕作应当成为防治东北黑土区土壤侵蚀的关键措施。

＜正＞Comparisons of sol.r magnetic fiel. observations in different spectral.l.nes （Howard and Stenfl., Sol.r Phys, 1972. V. 22. P.402;Stenfl., Sol.r Phys. 1973. V. 32. P.41;Ul.ich, ASP Conf. Ser. 1992.V.26.P. 265;etc.） and in different observatories （recent papers by Wenzl.r et al., Astron. Astrophys. 2004. V. 127. P. 1031;Tham et al., ap. J. Suppl. 2005. V. 156. Is. 2. P. 295） are crucial.important for understanding of sol.r magnetism nature, for mutual.instruments cal.bration and for some connected issues （exp., construction of common data sets for study of temporal.variations of different parameters: rotation, sol.r irradiance, open fl.x etc.）. In this report we expl.re the distribution across the sol.r disk of the magnetic strength ratios （MSr’s） in different combinations of spectral.l.nes using a Stokes-meter observations of l.rge-scal. magnetic fiel.s made at Sayan observatory, as wel. as of the MSr’s in different combinations of observatories （Sayan, Wil.ox sol.r observatory, Kitt Peak, SoHo/MDI, Mount Wil.on）. It was found that al.ng with expected center-to-l.mb variations （Cl.） of MSr’s when different l.nes are used, there are a significant pol.r-equatorial.asymmetries of Cl.’s in some cases. It is a quite new resul. that is important from different points of view （the geometry of magnetic fiel.s, the extrapol.tion of magnetic fiel.s to the corona, etc）. The resul.s of comparison of the experimental.MSr Cl.’s with 1.5D and 2D theoretical.simul.tions in the frame of two-component fl.x tubes model. are presented.

Pure and Zr, l. or Pr-doped cerium oxides were characterised by transmission el.ctron microscopy (TEM), N2 adsorption-desorption at –196 oC and X-ray diffraction (XrD). For crystal.sizes cal.ul.tion, the Scherrer and Wil.iamson-Hal. equations were compared, and the rel.tionship between surface area and crystal.size was critical.y discussed.
