白鸡屎藤挥发油抗肠炎沙门菌内毒素作用的分析

为了探讨白鸡屎藤挥发油抗肠炎沙门菌内毒素的作用,将420只7日龄三黄鸡随机分成A、B、C、D、E、F组并对A、B、C组鸡按100μg/mL(1mL)预防用药,在12日龄时对A、B、D、E组口服肠炎沙门菌攻毒,攻毒24h后对A、D组按100μg/mL白鸡屎藤挥发油1mL进行滴鼻给药治疗,同时将不同质量浓度的白鸡屎藤挥发油与内毒素混合对另外90只雏鸡进行肌肉注射攻毒,并进行试验鸡与攻毒鸡临床死亡情况统计、病理组织学观察和肝与血液生化指标测定。结果显示,白鸡屎藤挥发油对肠炎沙门菌内毒素具有灭活作用,可缓解血清ALT和AST活性的升高或使其降低(P<0.01或P<0.05),提升肝及血清中SOD的活性(P<0.01或P<0.05),使肝中MDA含量下降和延缓其升高。结果表明,白鸡屎藤挥发油具有抗肠炎沙门菌内毒素的作用,其机理与其保肝作用和抗氧化损伤作用有关。     

水域污染损害有关监测及评估鉴定问题

针对油污对海洋环境造成的生态损害和渔业资源损失索赔的实务问题,采用法定监测机构作出专业监测评估报告,为损害索赔提供技术依据的方法,从监测报告的特性、内容及其监测的方法,分析得出专业监测报告属于民事诉讼证据中的＂鉴定结论＂,应当作为认定损害的依据,并提出渔业主管部门对渔业资源损害的调查权和代表国家行使渔业资源损失的索赔权并存时并无利害关系的观点。     

论受害人对船舶油污责任保险人的直接请求权——兼谈《中华人民共和国海事诉讼特别程序法》第97条的立法完善

在船舶油污损害赔偿领域设置保险和保证赔偿制度是保护受害人充分赔偿的需要,也是特殊侵权损害赔偿制度发展的必然。船舶油污责任保险具有适用范围特定性以及保险的强制性等特点。船舶油污损害赔偿公约体系确立了受害人对油污责任保险人或保证人的直接诉讼制度,但有着特定的适用范围,并赋予了保险人较为宽泛的抗辩事由。《中华人民共和国海事诉讼特别程序法》借鉴国际公约,确立了受害人对油污责任保险人的诉讼制度,但由于缺乏配套制度,实践中该制度的适用比较混乱。建议中国建立以油污强制责任保险制度为核心的船舶油污责任制度,明定责任保险人直接被诉的情形,以及在直接被诉情形下的抗辩事由,同时明确责任保险人承担责任的形式等。     

Variation of δ2H, δ18O & δ13C in crude palm oil from different regions in Malaysia: Potential of stable isotope signatures as a key traceability parameter

A total of 33 crude palm oil samples were randomly collected from different regions in Malaysia. Stable carbon isotopic composition (δ¹³C) was determined using Flash 2000 elemental analyzer while hydrogen and oxygen isotopic compositions (δ²H and δ¹⁸O) were analyzed by Thermo Finnigan TC/EA, wherein both instruments were coupled to an isotope ratio mass spectrometer. The bulk δ²H, δ¹⁸O and δ¹³C of the samples were analyzed by Hierarchical Cluster Analysis (HCA), Principal Component Analysis (PCA) and Orthogonal Partial Least Square-Discriminant Analysis (OPLS-DA). Unsupervised HCA and PCA methods have demonstrated that crude palm oil samples were grouped into clusters according to respective state. A predictive model was constructed by supervised OPLS-DA with good predictive power of 52.60%. Robustness of the predictive model was validated with overall accuracy of 71.43%. Blind test samples were correctly assigned to their respective cluster except for samples from southern region. δ¹⁸O was proposed as the promising discriminatory marker for discerning crude palm oil samples obtained from different regions. Stable isotopes profile was proven to be useful for origin traceability of crude palm oil samples at a narrower geographical area, i.e. based on regions in Malaysia. Predictive power and accuracy of the predictive model was expected to improve with the increase in sample size. Conclusively, the results in this study has fulfilled the main objective of this work where the simple approach of combining stable isotope analysis with chemometrics can be used to discriminate crude palm oil samples obtained from different regions in Malaysia. Overall, this study shows the feasibility of this approach to be used as a traceability assessment of crude palm oils.

Diffusion of labor agreements: evidence from the UK oil industry

There has to date been no in-depth analysis of the way in which industrial relations practices – in particular labor agreements – diffuse vertically through an organization and horizontally through an economy. This is despite the titles of empirical research in this area. This process of diffusion however, is both an important and yet neglected area of theory. The theory of the diffusion of innovations can be applied to the empirical findings here and encompasses several previous studies: it thus enables a more thorough investigation of the way in which changes in industrial relations are promulgated both within and between organizations. This paper presents evidence of such a diffusion of innovation effect in the oil sector of the UK economy.     

Which Grievances Make People Support Violence against the State? Survey Evidence from the Niger Delta

Previous research has established a link between oil production and armed conflict in low- and middle-income countries. Oil-related grievances are viewed as a key variable driving resentment and antistate attitudes. However, the off-the-shelf measures of existing studies (oil exports, oil revenues per capita, etc.) measure dependence and richness, not grievances among the population. This article contributes to filling this gap. Relying on an original opinion poll from the conflict-ridden Niger Delta, the analysis shows that both rebel-pursued, collective grievances (unfair oil revenue distribution) and individual grievances (livelihood destruction due to oil production) make people support antistate violence. These results lend micro-level evidence to the grievance mechanism linking oil and (support for) rebellion.     

中国和印度在石油供给新来源上的竞争态势与合作动向

中国和印度经济的快速发展使两国对进口石油的依赖程度不断上升,两国在世界各地寻求新的石油供给来源的过程中形成相互竞争的态势。与此同时,中印双方也在探索进行合作的可能性,并出现了一些积极的动向。     

论油污应属巨灾保险承保对象

油污符合巨灾保险承保对象所具有的损失发生巨大性、风险发生概率低、风险预测难度大和风险难以分散的识别标准,应属于巨灾保险承保对象.油污巨灾保险具有公共产品属性、石油利益的获得者具有广泛性、侵权损害赔偿责任呈现社会化分担趋势,故政府应当作为油污巨灾保险的投保人.将油污纳入巨灾保险体系中,有助于丰富油污保险类型,构建油污巨灾保险与普通油污保险二元并列的局面,以社会力量督促石油行业提高安全生产力度,并达到弥补普通油污保险、油污基金、政府救济等其他油污灾后救济制度缺陷的目标.     

萨哈林岛大陆架油气开发对鄂霍次克海生态系的影响

萨哈林岛大陆架石油和天然气储量丰富。开发初具规模。萨哈林岛将成为庞大的石油天然气开发中心。但大规模地开发海底大陆架石油和天然气资源给海洋生态系造成危害极大。在石油和天然气开发的每个阶段和一切活动中都存在污染问题。萨哈林岛大陆架东北部水域的碳氢化合物含量远远高于可接受的含量。因此有必要采取一些有效的监控措施。
