Saline intrusion is a hot issue and has always been of concern in the VMD(Vietnamese Mekong Delta),especially in the context of many changes of impact factors such as upstream flows and SLR(Sea Levels Rise).Vulnerability to changes in the upstream flows and SLR ismust-have reasons for updated and interpreted *** information is used for exploiting of soil and water *** 11 model was successfully applied to assess the saline *** study provided the picture of the saline intrusion in the dry season from January to May in the VMD in the existing situation(2015 and 2016)and the future(2030 and 2050)under the impact of flow at Kratie in various frequencies of 18%,50%and 85%based on the time series of 2001-2016,and SLR according to RCP(Representative Concentration Pathway)4.5 scenario of MONRE(Ministry of Natural Resources and Environment)of Vietnam issued in *** results show that in the year 2015 the ASI(Saline Intrusion Area)in the VMD was relatively low due to moderate tidal level and high Kratie discharge(P=18%).The scenario like the situation in 2016 and in the future ASI increased significantly compared to the 2015 baseline scenario which shows that the VMD is very vulnerable to saline *** on multivariate regression analysis,the study also presented the formulas for the relationship between the ASI of 0.25 g/L,2.5 g/L and 4.0 g/L thresholds and the impact factors such as the average discharge at Kratie and the maximum daily tidal level in East Coast during the dry season from January to *** an adjusted R2 at 0.913-0.974,these formulas are believed to be reliable for predicting ASIs based on the Kratie flow and the East Coast tidal level.

作者： hamada S. Devys J.-M. thanh h.X. B. Plaud 王文军 Dept. d’Anesthesiologie Reanimation Fondation Ophtalmologique Adolphe R. 25-29 rue Manin 75019 Paris France Dr.

Objective: To determine the protective action of hyaluronidase on peribulbar anesthesia-related diplopia in patients undergoing cataract surgery. Design: Single-center observational case series. Participants: All patients undergoing elective phacoemulsification and intraocular lens implantation under peribulbar anesthesia between February 2001 and January 2003. Methods: We compared the incidence of postoperative diplopia between 2 periods-February 2001 to January 2002 (P1) and February 2002 to January 2003 (P2)-which differed by the presence (P1) or absence (P2) of hyaluronidase in the anesthetic solution. Main Outcome Measures: All patients were examined on the first and fifth postoperative days during both periods. When diplopia was diagnosed, we recorded the characteristics of the patient, peribulbar anesthesia, and diplopia (orthoptic examination, and magnetic resonance imaging in some cases). Results: Seven thousand two hundred five patients were studied. During P1, 3582 patients received peribulbar anesthesia, and no cases of diplopia occurred. During P2, 3623 patients received peribulbar anesthesia, and 27 cases of diplopia occurred (incidence, 0.75%; P=0.0002 vs. P1). Diplopia involved the inferior rectus (40%) and the external rectus (37%) muscles. Diplopia was persistent in 54%of the cases. Conclusions: Peribulbar anesthesia-related diplopia was significantly more frequent when hyaluronidase was not added to the anesthetic solution.

有机种植袋的开发应用可以克服塑料袋带来的污染土壤和移植时损害植物根系的缺点。通过加入椰子纤维来加强有机种植袋的韧性。该研究的主要目的是探讨三种木本植物Albizia julibrisin、Neolamarckia cadamba和Gmelina arborea采用有机种植袋育苗移栽的效果。对椰子纤维和水葫芦三种成分的有机植物袋进行了性能测试。为了解种植袋的性能,进行了两个阶段的试验。首先,从第0天至第50天,在苗圃期间进行50d的有机植物袋试验。其次,移栽后第60天、70天、80天对有机植物袋进行检测,并进行田间观察。该研究中的参数为株高、穿透有机种植袋的总根数以及在有机种植袋中生长并在田间移栽的植物的总叶数和茎径。结果表明,椰子纤维155g和水葫芦505g组成的有机种植袋(A3B3)的抗压强度为0.020 kg/cm2,具有最佳的植株生长速率。抗压强度影响穿透有机袋的根数。一般来说,有机种植袋中种子的生长速度比塑料袋里的要快。Albizia的生长速率(0.379 cm/d)高于Cadam和Gmelina。

【目的】阐明不同林地清理方式下(火烧清理和人工清理)生物炭和氮添加对桉树红锥混交林土壤养分的影响,为人工林的经营管理提供参考。【方法】在火烧清理和人工清理林地的桉树红锥混交林中,设置生物炭和氮添加的控制实验,研究生物炭和氮添加对土壤有机碳(SOC)、全氮(TN)、全磷(TP)、全钾(TK)、有效磷(AP)和有效钾(AK)含量的影响。【结果】不同林地清理方式下,生物炭和氮添加对林地土壤养分的影响存在差异:与对照相比,人工清理林地时,添加生物炭显著增加了20～40cm土层的AP含量;氮添加极显著增加了0～10cm土层的SOC、TP、AP含量和C∶N;10～20cm土层的SOC、AK含量,20～40cm土层的AP和AK含量也显著增加;而0～10cm土层的N∶P则极显著降低。林地清理方式为火烧清理时,生物炭添加极显著增加0～10cm土层的TP含量,而0～10cm、10～20cm土层的SOC和AK含量,0～10cm土层的C∶N,10～20cm的AP∶TP、C∶P以及0～10cm、10～20cm、20～40cm土层的AK∶TK显著降低,0～10cm土层的AP含量、AP∶TP、C∶P和N∶P更是极显著降低。氮添加显著降低10～20cm土层的N∶P以及0～10cm土层的AP∶TP,0～10cm土层的AP含量以及10～20cm的TN含量下降达到极显著水平。【结论】人工清理林地条件下,实施生物炭和氮添加有利于提高桉树红锥混交林的土壤养分。
