This paper provides a schematic summary of the topics during the lecture series by Professor Nicholas j. Conard at the Institute of Vertebrate Paleontology and Paleoanthropology, Chinese Academy of Sciences, focusing on the methodological issues and researches at four topics:1) Schoningen, 2) Sibudu and other Middle Stone Age(MSA) sites in South Africa, 3) excavations at Tonchesberg, Wallertheim and other Neanderthal sites, 4) the caves of the Swabian jura and the origins of art and music. knowledge of excavation methods of his team, archaeological material in a broader context, and research achievements based upon the sites he is working on were shared by the lecture series. The lectures were also intended to foster international cooperation in teaching and research in future.

Geomechanics of subsidence above single and multi-seam coal mining

引用

journal of rock Mechanics and Geotechnical Engineering 2016年第3期8卷 304-313页

作者： A.M.Suchowerska Iwanec j.P.Carter j.P.Hambleton Golder Associates SydneyAustralia ArC Centre of Excellence for Geotechnical Science and Engineering The University of NewcastleNewcastleAustralia

Accurate prediction of surface subsidence due to the extraction of underground coal seams is a significant challenge in geotechnical engineering. This task is further compounded by the growing trend for coal to be extracted from seams either above or below previously extracted coal seams, a practice known as multiseam mining. In order to accurately predict the subsidence above single and multi-seam longwall panels using numerical methods, constitutive laws need to appropriately represent the mechanical behaviour of coal measure strata. The choice of the most appropriate model is not always straightforward. This paper compares predictions of surface subsidence obtained using the finite element method, considering a range of well-known constitutive models. The results show that more sophisticated and numerically taxing constitutive laws do not necessarily lead to more accurate predictions of subsidence when compared to field measurements. The advantages and limitations of using each particular constitutive law are discussed. A comparison of the numerical predictions and field measurements of surface subsidence is also provided.

作为整个食品安全的重要组成部分,食品安全的重要性早在1992年国年营养会议和1996年世界食品峰会就已经被许多国家的政府认识到了。最近欧盟（EU）颁布了食品安全的法律（178/2002）。食品的质量和安全受许多因素的威胁,包括天然毒素。在广阔的天然毒素范围内,真菌毒素是研究得最广泛的,并且引起了高度的关注,因为它们普遍存在并且对人体和动物健康存在着潜在危害。真菌毒素由某些真菌类产生,它在有利的温度和湿度条件下,入侵农田里的大范围农作物,并入侵收获季节后的生产产品。1994年欧盟（EU）在他们的食品科学委员会对几种真菌毒素:黄曲酶毒素,棕曲霉毒素,棒曲霉素和脱氧雪镰刀菌烯醇发表观点后起动了调整食品中某些真菌毒素标准化的进程。
