一体化PET/MRI通过一站式成像提供肿瘤解剖学及功能评估,且与^(18)F-FDG PET/CT相比其辐射暴露量减少80%,因此对癌症患儿的分期与再分期具有显著临床价值。该文回顾了^(18)F-FDG PET/MRI在小儿肿瘤中的临床应用,尤其关注PET/MRI在患儿管理中的价值。来自4个不同机构的PET/MRI应用先行者分享了他们对PET/MRI技术在癌症患儿评估中特殊优势的见解。文章作者讨论了全身PET/MRI在评估某些解剖区域(如软组织和骨髓)中的价值以及儿童特殊的PET/MRI影像学特征,并强调了全身PET/MRI如何通过在不失去诊断准确性的同时减少所需放射学检查次数(因此减少辐射暴露),改善淋巴瘤、肉瘤和神经纤维瘤病患儿的临床管理。文章论述了PET/MRI如何帮助区分恶性肿瘤与感染性或炎性疾病;另外,简要探讨了PET/MRI用于接受免疫治疗的患儿疗效评估以及对不同诊疗一体化药物评估的未来研究方向。从儿童应用中所获得的经验也可拓展至成人患者的评估中。

The winemaking process involves the genera- tion of a significant amount of waste and wastewater. These residues should be addressed for recycling or treatment before being returned to environment. As each winery is unique in waste generation and disposal, plans for environmentally friendly waste management are not universal and should be tested for their effectiveness. In this study, a diagnostic was made during three years, in different wineries, throughout Portugal, in order to quantify and characterize the waste and the wastewater produced. The results showed that solid waste and wastewater are mainly produced during the harvest period, corresponding to 74% and 87%, respectively. One ton of processed grape approximately produce 0.13 t marc, 0.06 t lees, 0.03 t of stalks and 1.65 m3 of wastewater. No significant differences （P≤0.05） were observed for grape marc, lees and wastewater ratios, between years or wineries. With respect to the stalk ratio, there was no effect of year but the winery significantly affected this ratio （P ≤ 0.05）. During the study period the treated wastewater, since diluted, revealed suitable characteristics for irrigation representing an additional source of water. In this regard, the data acquisition and consolidation ensure the transfer of information and experience which constitute an essential step in a support decision tool design.

为定量表征淮北煤田中高阶煤储层物性特征，采用工业分析、显微煤岩组分定量、低温氮吸附、高压压汞、核磁共振等实验手段，对淮北煤田7个煤样的物性特征进行了研究。结果表明，淮北煤田煤显微组分以镜质组为主，最大镜质组反射率变化较大，在0.7%-2.5%之间，可能受燕山期郯庐和太行山岩浆活动的共同影响。该煤质具有中-高灰分、低-极低硫含量、低磷、中高热值的特点。从低阶煤到中阶煤，由于脱水作用较强，煤基质收缩，吸附孔隙和渗流孔隙体积减小，裂隙体积增大；从中阶煤到高阶煤，吸附孔具有明显的优势，表明其对甲烷的吸附能力增强。预测淮北煤田宿县矿区的南坪深部、桃园祁南深部、彭桥深部、朱仙庄北部，临涣矿区的任楼赵集深部、许疃深部，濉萧矿区的萧西深部为该区煤层气勘探的较有利区，

The Sendai Framework for Disaster Risk Reduction 2015–2030(SFDRR) represents an inclusive approach to disaster risk reduction, linked to development and recovery. Building on previous international guidelines, the SFDRR promotes practical and measurable outcomes for reducing disaster losses, including indicators to measure progress towards seven specific global *** in the context of the priorities and global targets of the SFDRR, the article considers the case of the Great East Japan Earthquake and Tsunami of 2011 to illustrate advances and limitations in pre-disaster tsunami hazard engineering and post-disaster recovery. With respect to the targets set out in the Sendai Framework related to risk reduction and tsunami engineering, especially Priority 1,understanding disaster risk, there have been significant advances in hazard assessment and systems for tsunami detection and warning. Although the SFDRR emphasizes actions in the recovery phase through Priority 4, enhancing disaster preparedness with an emphasis on the concept of build back better, on its own this does not function as a clear directive for guiding recovery. However, the overall people-centered and inclusive approach of the SFDRR, as well as the global targets and several sub-priorities, can be a useful way to shape good practices in recovery and evaluate recovery progress.

Hydrologic performance of bioretention systems is significantly influenced by the media composition and underdrain configuration. This research measured hydrologic performance of column-scale bioretention systems during a synthetic design storm of 25.9 mm, assuming a system area：catchment area ratio of 5%. The laboratory experiments involved two different engineered media and two different drainage configurations. Results show that the two engineered mediawith different sand aggregates were able to retain about 36% of the inflow volume with tree drainage conlaguratlon. However, the medium with marine sand is better at delaying the occurrence of drainage than the one with pumice sand, denoting the better detention ability of the former. For both engineered media, an underdrain configuration with internal water storage （IWS） zone lowered drainage volume and peak drainage rate as well as delayed the occurrence of drainage and peak drainage rate, as compared to a free drainage configuration. The USEPA SWMM v5.1.11 model was applied for the tree drainage configuration case, and there is a reasonable fit between observed and modeled drainag.e-rates when media-specific characteristics are available. For the IWS drainage configuration case, air entrapment was observed to occur in the engineered medium with manne sand. F^lhng ot an IWS zone is most likely to be influenced by many factors, such as the structure of the bioretention system, medium physical and hydraulic properties, and inflow characteristics. More research is needed on the analysis and modeling of hydrologic process in bioretention with IWS drainage configuration.

International Journal of Disaster Risk Science 2014年第3期5卷 242-246页

In recent years, there has been a growing need to address loss and damage as a result of climate change through international processes. At the most recent November 2013 international climate change talks in Warsaw, 194 countries negotiated the best way to establish institutional arrangements for loss and damage under the United Nations Framework Convention on Climate Change. Such a decision to establish these arrangements was made in 2012 in Doha in a decision known as the‘‘Doha Gateway.’’ While the 19th(2013) Conference of the Parties succeeded in delivering the Warsaw International Mechanism for Loss and Damage Associated with Climate Change Impacts, there was concern by some negotiators earlier into the conference that this would never transpire given the staunch disagreements between countries and lobbying blocks on a way forward. This article provides a brief historical overview of loss and damage at the climate change talks, and examines the key discourses defining this issue between 2011 and 2013 by analyzing submissions by lobbying blocks and member countries, and final negotiated texts. These discourses revolve around causality and solutions, compensation, and the relationship between loss and damage and adaptation.
