Abstract Nineteenth‐century Palestine mapping projects based on systematic land surveying reached a peak with the Ordnance Survey of Western Palestine between 1871 and 1877, conducted on behalf of the Palestine Exploration Fund by officers of the British Royal Engineering Corps. Various other nineteenth‐century proposals for an organized survey of the country—some of which bore partial results while others were never implemented—are also presented. The surveying of one region, Mesopotamia, during the 1830s and 1840s, forms the basis for the discussion of the reasons for the relative lateness of the topographical survey. The sacredness of the region seems not to have been a sufficiently convincing motive for entrepreneurs to organize and finance such a survey. The main reason for the delay in mapping the country as a whole was that it was not especially important, either strategically or geo‐politically, for the European nations engaged in the international struggles in the Middle East until the last quarter of the nineteenth century. 相似文献

Examples of early astogeny in the species Carinatocella harmeri (Stach), Costaticella hastata (Busk) and Claviporella aurita (Busk) are discussed. The primary zoid differs in each species and if found fossil, only in C. hastata could this zoid be recognised as a bryozoan fragment. Analogous development in other Bryozoa is discussed. 相似文献

Northwestern Italian weak-motion data were used to study attenuation characteristics of horizontal peak ground acceleration (PGA) and horizontal peak ground velocity (PGV) from earthquakes of local magnitudes (M l ) up to 5.1. Data have been provided by the RSNI (Regional seismic network of Northwestern Italy) and RSLG (Regional seismic network of Lunigiana-Garfagnana) waveform database. The database consists of more than 14000 horizontal components recorded in the period 1999-2002 by both broadband and enlarged band seismometers. The accuracy of the procedure used to extract PGA values from the velocity recordings was verified comparing observed and derived PGA values at station STV2, which was equipped with both a temporary K2 Kinemctrtcs accelerometer and Guralp CMG40 broadband sensor. The attenuation of both peak ground acceleration and peak ground velocity was found to be logarithmically distributed with a strong attenuation for low distances (less than 50 km) and low M l values (<3.0). The resulting equations are: Log(PGA)=?3.19+0.87M?0.042M 2?1.92 Log(R)+0.249S, Log(PGA)=?4.23+0.76M?0.018M2?1.56 Log(R)+0.230S, where PGA is expressed in g, PGV is expressed in m/s, M is local magnitude, R is the hypocentral distance in kilometers and S is a dummy variable assuming values of 0 and 1 for rock and soil respectively. For increasing distance and magnitude, both PGA and PGV values show a linear distribution. The validity range of the obtained attenuation relationships is 0–200 km for distances and M l up to 4.5. Sensitivity studies performed by analysis of residuals, showed that predicted PGA and PGV values are stable with respect to reasonable variations of the model and distances providing the data. Comparisons with attenuation relationships proposed for Italian region, derived from strong motion records, are also presented. 相似文献

The First World War was the first modern, mediated conflict. In this paper I argue that British correspondents on the Western front attempting to accurately witness the war encountered a crisis of representation and visuality. They occupied a particularly unstable position between the many sites and points of view within a cubist landscape of shattered geographies and unstable boundaries. Their writings, though rich in masculinist and nationalistic accounts of heroism, also contain a newer perspective characterized by the failure to fit these older narratives into the inhuman, incomprehensible spaces of modern war. 相似文献

广州西汉南越王墓和徐州狮子山汉墓是我国汉代最重要和出土玉器数量最多的两个王侯级墓地,两墓出土的丝缕和金缕玉衣是当时南方和中原汉王朝最重要的墓葬玉器之一。通过上手观察、显微镜拍照并利用环境扫描电镜和漫反射红外光谱、拉曼光谱技术对广州南越王墓及徐州狮子山汉墓出土玉衣部分玉片的质材和加工工艺进行了观察测试和对比分析。结果显示,两地玉衣的玉料均主要为透闪石质,从现存玉衣颜色及玉质结构上看,徐州狮子山汉墓出土玉衣玉料来源单一且玉质明显好于南越王墓,南越王墓玉料具有多来源的特征,玉衣中的“假玉”可能来自粤西。从南越王墓玉衣片部分切割痕迹判断,南越王墓所使用的切割工具可能接近当时的最高水平,也可能存在中原交换来源的玉材,无法排除南越王墓玉衣全部或部分在当地制作的可能;南越王墓和徐州狮子山汉墓出土玉衣加工工艺特征明显不同,显示两地玉衣系由不同 “玉作”体系加工完成,汉代可能存在多个不同的玉作体系,工艺水平参差不齐。 相似文献
