The constant rate of supply (CRS) of excess 210Pb model was successfully applied to assess 210Pb data of two sediment cores from the lake Qattinah, Syria. Gamma spectrometry was used to determine 137Cs and 210Pb activity concentrations. The bottom of the cores was 210Pb-dated to years 1907 and 1893. The accumulation rates were determined using 210Pb method and found to vary similarly in both cores from 0.10 ± 0.01 to 3.78 ± 0.57 kg m?2 y?1 during the past century. 137Cs was used as an in-dependent chronometer. The two distinct peaks observed on the 137Cs record of both cores, corresponding to 1965 and 1986, have allowed a successful validation of the CRS model. 相似文献

The 1997 Asian financial crisis has been a debilitating experience for the ASEAN countries, with attendant political transformation and economic readjustment. Regional unity has also been affected: ASEAN appears to lack resolve and cohesion as well as the ability to forge common action. While political change has been effected and more open systems are in place, ASEAN countries now seem set to bounce back with renewed vigour and a business-as-usual approach to their economies. However, ASEAN's revitalization into the next century will significantly depend on the region's most important polity, Indonesia, the country most affected by the crisis and now undergoing substantive change. 相似文献

This article is the first of two companion articles that evaluate the seismic hazard in northwestern Pakistan. The area, located at the western edge of the Himalayas, has numerous active faults including the Main Boundary Thrust (MBT) and Main Mantle Thrust (MMT). This article describes the methodology used to perform regional deterministic and probabilistic seismic hazard analyses. Here, seismic sources were defined from 32 identified faults while prior studies have been based on diffuse seismicity and areal source zones. Fault parameters were selected using available data and empirical correlations for faults elsewhere. Recurrence relations were constructed for all discrete faults based on both historical and instrumented seismicity in addition to geologic evidence. Due to lack of region specific attenuation relationships, four plate boundary attenuation relations from the Next Generation Attenuation of Ground Motions Project [Abrahamson et al., 2008] were employed to predict ground motions. Predicted ground motion parameters are compared to measurements from the recent 2005 Kashmir earthquake. In the companion article, the methodology developed and evaluated here is used to conduct deterministic and probabilistic seismic hazard analyses for the entire study region. 相似文献

The paper consists of six parts. The first part discusses the major reasons for the presence of a conventional sociopolitical Baloch culture in Iran. The second part presents a profile of the Iranian Baloch elites, dividing them into four major groups: the Sunni clerics or molavis, tribal chiefs, the educated, and the wealthy. The third discusses the challenging relationship which exists among the Baloch elites. The fourth describes the elites' attitudes towards the Baloch society's norms. The fifth determines the elites' orientation towards state and politics. And finally the paper ends with conclusions. 相似文献

This paper presents an empirical study conducted in a small traditional city, Salt, Jordan. An investigation was made to examine residents' ‘images of the past’. The objective was to identify building attributes that influence these residents' images. A survey research design using multiple sorting tasks with open‐ended questions was used to identify these building attributes. The images were elicited through the observation of coloured photographs of a sample of older buildings in the city centre. Images of the past were examined within three content areas: knowledge of the past; date of construction; and character of the past of Salt City. The building attributes investigated were: contour, size, shape, surface quality, signage, visibility, use, and significance. The results of the study suggest that older buildings in the centre of the city evoked similar images of the past focused on public or social buildings along with residential settlement building. Attributes relating to images of the past were original use, date of construction, historic signage, and historic integrity. This study presents an approach for operationalising an image of the past. 相似文献
