Multilateralism in the Straits of Malacca and Singapore

This paper analyzes International Maritime Organization (IMO) involvement in maritime cooperation regime in the Straits of Malacca and Singapore through multilateralism. It begins by introducing the maritime cooperation regime prior to 2001, which was mainly trilateral in nature through Tripartite Technical Expert Group on the Safety of Navigation (TTEG). Although TTEG managed to increase the level of safety of navigation in the Straits of Malacca and Singapore through the implementation of the Traffic Separation Scheme (TSS) in 1981 and Mandatory Ship Reporting System (STRAITREP) in 1998, such cooperation was beset by financial strain and conflict of interests. Subsequently, there was a change in the cooperation regime after 9/11 incident. This paper identifies that the change was contributed by the IMO through a methodology called multilateralism. Three important principles were adopted by IMO in implementing multilateralism in the Straits of Malacca and Singapore, namely generalized principles of conduct (respect for sovereignty and compliance with burden sharing principle under Article 43 of UNCLOS 1982), diffuse reciprocity, and indivisibility. This paper concludes that multilateralism by IMO has transformed trilateral cooperation into multilateral cooperation in the Straits of Malacca, combining state actors (littoral states and user states) and non-state actors (non-governmental organizations and international shipping industries).

Atmospheric nitrogen inputs into the North Sea: effect on productivity

The ANICE (Atmospheric Nitrogen Inputs into the Coastal Ecosystem) project addressed the atmospheric deposition of nitrogen to the North Sea, with emphasis on coastal effects. ANICE focused on quantifying the deposition of inorganic nitrogen compounds to the North Sea and the governing processes. An overview of the results from modelling and experimental efforts is presented. They serve to identify the role of the atmosphere as a source of biologically essential chemical species to the marine biota. Data from the Weybourne Atmospheric Observatory (UK) are used to evaluate the effect of short episodes with very high atmospheric nitrogen concentrations. One such episode resulted in an average deposition of 0.8 mmol N m⁻² day⁻¹, which has the potential to promote primary productivity of 5.3 mmol C m⁻² day⁻¹. This value is compared to long-term effects determined from model results. The total calculated atmospheric deposition to the North Sea in 1999 is 948 kg N km⁻¹, i.e. 0.19 mmol N m⁻² day⁻¹ which has the potential to promote primary productivity of 1.2 mmol C m⁻² day⁻¹. Detailed results for August 1999 show strong gradients across the North Sea due to adjacent areas where emissions of NO_x and NH₃ are among the highest in Europe. The average atmospheric deposition to the southern part of the North Sea in August 1999 could potentially promote primary production of 2.0 mmol C m⁻² day⁻¹, i.e. 5.5% of the total production at this time of the year in this area of the North Sea. For the entire study area the atmospheric contribution to the primary production per m² is about two-third of this value. Most of the deposition occurs during short periods with high atmospheric concentrations. This atmospheric nitrogen is almost entirely anthropogenic in origin and thus represents a human-induced perturbation of the ecosystem.     

化学注浆治理巨厚表土层立井井壁漏水

煤矿立井由于各种原因经常发生井壁渗漏水,严重影响正常的煤矿安全生产。邱集煤矿副立井表土层厚320m,为巨厚表土层,发生渗水后,采用改性脲醛树脂浆材成功进行了破壁注浆处理,将井筒的涌水量由10m3/h降至0.3m3/h左右。同时,注浆时浆液形成的帷幕能达到加固地层,减少地层压缩沉降量,排除生产安全隐患,保护井桶的作用。

东营凹陷高青-平南断裂带幔源流体活动特征及其成藏效应

东营凹陷高青-平南断裂带为幔源流体运移的主要通道,该幔源流体主要为岩浆(岩)和CO2气体。高青-平南断裂带幔源流体活动方式和活动强度存在着时间和空间上的差异,该断裂带在古近纪-新近纪至少经历了四期富CO2幔源流体活动。高青-平南断裂带富CO2幔源流体对油气成藏的影响主要表现在：①直接形成无机CO2气藏;②通过能量——热的作用和物质,即CO2的加入,影响水-岩相互作用的强度和方向,从而改善油气储集层的物性;③在一定程度上提高源岩的排烃效率,增加油气的运移速率。
