2014年8月,美国国家食源性疾病分子分型监测网络（national molecular subtyping network for foodborne disease surveillance）———PulseNet,发现多个州出现纽波特沙门菌血清型聚集性感染,检测到的脉冲场凝胶电泳（pulse-field gel electrophoresis,PFGE）带型（限制性内切酶Xba I,带型为JJPX01.0061）难以鉴别。与疾病暴发相关的PF-GE带型曾与德玛瓦半岛地区弗吉尼亚东海岸生产销售的西红柿具有相关性,但尚未发现与黄瓜或其他农产品的相关性。

1919年在气象学上是重要的一年,不仅因为美国气象学会成立于这一年,同时还有其他两个原因。其中之一是J.皮叶克尼斯关于温带气旋结构的论文于1919年发表,建立了著名的挪威气旋模型。也是在那一年,一系列会议的举办促进了温带气旋研究所需的国际合作和科学交流组织的形成,这必然包括跨越国界的空间尺度。本章主要描述针对温带气旋的形成、演变和动力过程,它们构成的锋,以及伴随而来的急流和风暴路径进行科学探究的历史。我们将这些现象统称为气象学的核心,因为在此期间,其在促进气象学研究方面发挥着核心作用。这个成果丰硕的世纪使得温带气旋研究成为可能,是因为1)解决不良预报的实际挑战具有巨大的社会经济影响,2)理论、观测和诊断(包括动力模式)的结合提供了改进的物理解释和概念模型,以及3)强有力的国际合作。气旋的概念框架产生于对气旋分类和理解的渴望;它们包括挪威气旋模型和Shapiro-Keyser气旋模型。理解气旋动力学的挑战引申出诸如准地转、斜压不稳定、半地转和锋生等理论框架。预测爆发性温带气旋的挑战尤其带来了新的理论发展,如位势涡度(PV)理论和上游效应。对可预报性的局限性的更深层次的认识源于混沌决定论的演变。最后,观测的洞察力成就了详细的气旋和锋面结构、风暴路径及雨带分类。

关于人类和环境相互关系的传统观念正在迅速改变。那种认为人类与自然是相互隔离的,自然资源是取之不尽用之不竭的,而且认为世界是稳定的、可以预测的并且是平衡的旧观点已经过时了。在动态的社会-生态景观中强调学习和灵活性管理为基础的适应性方法的新的理念框架已经迅速初现端倪。我们以两个典型的世界遗产地区(大堡礁和大峡谷)为案例来研究如何在自然资源管理中通过改善科学和社会两个方面的结合来指导多尺度管理系统的变革从而应对和处理人类越来越占据主导的世界中出现的不确定性、风险和变化。

为了实现缩短出钢时间从而提高碱性氧气转炉(BOF)的生产效率,与熔融分析控制相关的过程如停吹、提枪或倾炉都要避免。为了达到这个目标,建立了一种用于控制BOF过程的新方法。该方法采用了一种新颖的、可在吹炼过程中进行炉渣和钢同时收集的非均相取样器,并应用了为此专门设计的激光分析方法(LIBS)。使用该方法,目标是尽可能快地完成非均相取样器收集的炉渣和钢的分析(Fe,C,P,S等元素)。除了建立非均相临线取样方法外,还建立了一种基于LIBS的特殊分析程序,当分析过程中移动非均相样品时,用于识别来自炉渣和钢的激光光束。与冶金模型相结合,由非均相取样器得来的数据经过处理后,可动态评价精炼进展状况并规定矫正行为,从而实现安全直接的出钢。预期的效益在于减少再吹炼的比率、节省出钢时间(预计每炉能缩短23min),同时延长耐火炉衬的寿命,提高生产产量。

AIm： To evaluate accuracy of in vivo diagnosis of ad- enomatous vs non-adenomatous polyps using/-SCAN digital chromoendoscopy compared with high-definition white light. mETHODS： This is a single-center comparative effec- tiveness pilot study. Polyps （n = 103） from 75 average- risk adult outpatients undergoing screening or surveil- lance colonoscopy between December 1, 2010 and April 1, 2011 were evaluated by two participating en- doscopists in an academic outpatient endoscopy center. Polyps were evaluated both with high-definition white light and with/-SCAN to make an/n vivo prediction of adenomatous vs non-adenomatous pathology. We de- termined diagnostic characteristics of/-SCAN and high- definition white light, including sensitivity, specificity, and accuracy, with regards to identifying adenomatous vs non-adenomatous polyps. Histopathologic diagnosis was the gold standard comparison. RESULTS： One hundred and three small polyps, de- tected from forty-three patients, were included in the analysis. The average size of the polyps evaluated in the analysis was 3.7 mm （SD 1.3 mm, range 2 mm to 8 mm）. Formal histopathology revealed that 54/103 （52.4%） were adenomas, 26/103 （25.2%） were hyper- plastic, and 23/103 （22.3%） were other diagnoses in- clude ＂lymphoid aggregates＂, ＂non-specific colitis,＂ and ＂no pathologic diagnosis.＂ Overall, the combined accu- racy of endoscopists for predicting adenomas was iden- tical between/-SCAN （71.8%, 95%CI： 62.1%-80.3%） and high-definition white light （71.8%, 95%CI： 62.1%-80.3%）. However, the accuracy of each endosco- pist differed substantially, where endoscopist A demon- strated 63.0% overall accuracy （95%CI： 50.9%-74.0%） as compared with endoscopist B demonstrating 93.3% overall accuracy （95%CI： 77.9%-99.2%）, irrespective of imaging modality. Neither endoscopist demonstrated a significant learning effect with i-SCAN during the study. Though endoscopist A increased accuracy using/-SCAN from 59% （95%CI： 42.1%-74.4%） in the first hal

A silver removal process was carried out on a Pb-Ag alloy through zinc powder injection of three different sizes （3.55, 44.4 and 734.8μm） with a top submerged lance using nitrogen as carrying gas. The higher silver removal was obtained for the zinc powder size of 44.4μm, while the lowest silver removal efficiency was attained for the smaller particle size. The AgZn phase was detected in the slag for the 44.4 and 734.8μm particle sizes by XRD, which was in agreement with SEm-EDS analysis. Experimental behavior was explained according to the melting and residence time of the injected particles.
