Risk assessment of sour gas inter-phase onshore pipeline using ANN and fuzzy inference system – Case study: The south pars gas field

Nowadays, pipelines have been extensively used for transporting oil and gas for long distances. Therefore, their risk assessment could help to identify the associated hazards and take necessary actions to eliminate or reduce the risk. In the present research, an artificial neural network (ANN) and a fuzzy inference system (FIS) were used to prepare a new model for pipeline risk assessment with higher accuracy. To reach this objective, the Muhlbauer method, as a common method for oil and gas pipeline risk assessment, was used for determining important and influential factors in the pipeline performance. Mamdani fuzzy model was developed in Matlab software by considering expert knowledge. The outcomes of this model were used to develop an ANN. To verify the developed model, the inter-phase shore pipe of phase 9–10 refinery in the South Pars Gas field was considered as a case study. The results showed that the proposed model gives a higher level of accuracy, precision, and reliability in terms of pipe risk assessment.

Listing for change? Exploring the politics of relief lists in Bangladesh after Cyclone Sidr

Ideal notions of efficient aid are challenged continuously by realities on the ground in the wake of major disasters, such as dire needs, limited resources, and opportunism. This paper demonstrates how ‘relief lists’ can be productive entry points for a systematic inquiry into the pervasive politics of disaster assistance. Through an analysis of qualitative data collected during the five years after Cyclone Sidr struck Bangladesh on 15 November 2007, it examines how relief lists featured in both physical and phantom forms and then developed beyond their transparency-making aims, becoming elevated sites of struggle for post-disaster resources. Three list processes, selected to indicate the temporal, material, and spatial dynamics of relief encounters, are assessed in depth. Although recipients of cyclone relief appreciated its value, the paper argues that list politics also stimulated structures of vulnerability, including inequality. Gradually, relief, as governed after Sidr, also served to restore the differential vulnerability of the country's coastal poor.     

Studies on polycyclic aromatic hydrocarbons in two sediment cores from the huaxi reservoir,china: Assessment of levels,sources, and ecological risk

This study investigated the levels, sources and ecological risks of 16 polycyclic aromatic hydrocarbons (PAHs) in two sediment cores that were collected along the Huaxi Reservoir. The spatial distributions and residue levels of the 16 priority PAHs in the sediments from the Huaxi Reservoir were analyzed for their potential ecological risk, source apportionment and contribution to the total PAH residue. The concentration level of the total PAHs (TPAHs) was in the range 1805 ng·g^?1 to 20023 ng·g^?1 based on dry weight, and the content of PAHs in the Huaxi Reservoir exhibited a gradual upward trend. The PAH congener ratios fluoranthene/(fluoranthene + pyrene) and indeno[1, 2, 3-cd]pyrene/(indeno[1, 2, 3-cd]pyrene + benzo[g, h, i]perylene) were used to identify the source. The main source of the low molecular weight PAHs was wood and coal combustion, whereas the high molecular weight PAHs were primarily from petroleum combustion sources. The results of an ecological risk assessment demonstrated that ACE poses a potential ecological risk, while FLU, NAP, ANT, BaP, DBA, PHEN and PYR can have serious ecological risks.     

The importance of context for effective public engagement: learning from the governance of waste

This paper takes a new look at the importance of context – institutional and political – in effective public engagement processes. It does so through a rare comparative opportunity to examine the effectiveness of processes of public engagement in two UK waste authorities, where the same waste company was involved as both the primary contractor for the delivery of the waste management service (including new energy-from-waste facilities) and, furthermore, the same staff delivered the public engagement. Interrogating these cases affords the opportunity to place flesh on the bones of the sometimes ‘abstract’ skeleton of context. While engagement processes support effective local governance in an era of partnerships and deliberative democracy, the paper identifies that the methods adopted cannot be played out devoid of detailed understanding and response to local context, including the strength of partnership working between the public and private sector, the degree of political support for engagement, and the extent to which a traditional institutional paternalism still dominates.

Predicting molybdenum toxicity to higher plants: Estimation of toxicity threshold values

Four plant species (oilseed rape, Brassica napus L.; red clover, Trifolium pratense L.; ryegrass, Lolium perenne L.; and tomato, Lycopersicon esculentum L.) were tested on ten soils varying widely in soil properties to assess molybdenum (Mo) toxicity. A larger range (66-fold-609-fold) of added Mo concentrations resulting in 50% inhibition of yield (ED₅₀) was found among soils than among plant species (2-fold-38-fold), which illustrated that the soils differed widely in the expression of Mo toxicity. Toxicity thresholds based on soil solution Mo narrowed the variation among soils compared to thresholds based on added Mo concentrations. We conclude that plant bioavailability of Mo in soil depends on Mo solubility, but this alone did not decrease the variability in observed toxicity enough to be used in risk assessment and that other soil properties influencing Mo toxicity to plants need to be considered.     

Transboundary governance of the Curonian Spit World Heritage Site

This study describes the governance and management structures of the Curonian Spit World Heritage Site, a transboundary protected area shared by Lithuania and the Russian Federation. Focusing on the national park authorities it presents the site from a local administrative perspective. The paper shows that due to strong state level influence and a lack of full stakeholder inclusion, different philosophies and priorities on both sides of the border challenge common management efforts and co-operation. Presenting the existing problems the paper points out the need for increased efforts at the state level as well as for the full inclusion of local communities to remove obstacles and foster co-operation. Hence, by adapting to certain environmental and transboundary governance principles, conflicts can be avoided and better results achieved.     

“地球工程”作为减缓气候变化手段的几个关键问题

减缓气候变化可以在大的地理尺度上以工程技术手段来实施。地球工程包括所有能源生产和消费以外的、不涉及工业生产过程管理的,在较大的地球尺度或规模上,去除大气中的CO2或直接控制太阳辐射而降温的各种人为的工程技术手段,主要包括三大类:绿色生物技术手段、碳捕获与埋存技术和太阳光辐射额度控制管理技术。这一类地球工程手段有着一系列经济、技术、环境、伦理、安全和不确定性含义。本文就近年来国际上关于地球工程作为减缓气候变化可能技术选择的几个关键问题开展了分析和讨论,涉及概念界定、技术特点、可能影响、治理构架等。作者认为,对于直接作用于碳的地球工程手段,如绿色生物技术手段和碳捕获与埋存技术,风险小、可操控;太阳光辐管理技术,通过人为排放到大气的SO2和气溶胶等的降温效应,来控制地球气温的上升,尽管使用的经济成本可能不高,具有实际操作可能,但其巨大的不确定性和可能的安全含义,需要引起足够的重视。从伦理上看,当代人是否有权来开展太阳光辐管理技术这类具有巨大科学不确定性的地球工程存在争议,在科学不确定的情况下采取任何行动,就失去了伦理学基础。从法律上看,人工干预太阳辐射,即使是科学实验或研究,由于其影响超出了国界,超出了当代人,也超出了人类社会,如果有人采取行动,也存在法律依据上的质疑。人工干预太阳辐射的研究和实施,需要一个国际治理构架。为了防止其他国家单独行动,需要"相互约束"的治理构架——"自我约束"以换取他国同意"自我约束"。鉴于气候变化和光辐管理在科学上的不确定性,目前不宜实施,短期内也不会提上议事日程。太阳光辐管理技术影响的复杂性和气候变化风险的迫切性,需要我们加大科学研究力度,为科学决策提供依据。中国作为一个新兴经济体,世界第一大CO2排放国,地域空间气候条件存在巨大差异性。从减排成本的角度,从气候影响的空间差异性,开展地球工程的科学研究,有着科学、政策和国际气候外交的积极意义。但是,相关的科学研究需要国际制度构架。由于气候变化框架公约及其谈判尚未涉及,需要开展系统科学、技术、经济、法律和国家安全等方面的相关研究,提高科学认知度,为国际谈判和政策选择提供决策依据。
