锦州20-2凝析油气矿井底原油的危害及处理办法

锦州20-2凝析油气矿井底出现原油后,生产工艺流程的控制阀、滤网、流量计等无法正常工作;压控失灵,容器憋压,乙二醇回收装置失控,损耗增加,影响生产。为此,增加一套原油与乙二醇水溶液分离装置,保证了乙二醇的供应量,从而维持了正常生产。     

格瑞克柿庄南枣园煤层气集输管网优化的PIPEPHASE数值模拟研究

格瑞克柿庄南枣园煤层气田具有典型的低产、低压、低渗的特征,由于目前国内既没有煤层气田设计的相关规范,又没有更多的经验可以借鉴,若采用传统的集输工艺必将造成工程投资的增加,降低整体经济效益。文章结合该气田集输管网的现状,运用PIPEPHASE数值模拟软件,研究出了一套经济适用的"集中增压‘枝上枝’阀组布站"的环形集输工艺技术。该技术具有投资省、见效快、便于管理维护、节省人员、建设灵活、节能、环保和占地少等优点,对国内今后大型低压、低产煤层气田的地面开发建设具有推广意义。

热膨胀量计算在离心压缩机组冷态对中数值验证中的应用

石化装置中由汽轮机驱动的离心压缩机组应用十分广泛,在运行过程中,由于驱动机与被驱动机的膨胀量不同,使热态时设备不能良好对中,造成设备内件失效,整机过早损坏。文章以镇海炼化富气压缩机组为例,介绍运用热膨胀量的计算解决在设备的安装过程中碰到的冷态对中数值验证的实际问题,以确保机组在热态时的良好对中。     

Enabling Energy Efficient Sensory Data Collection Using Multiple Mobile Sink

Mobile sink is the challenging task for wireless sensor networks （WSNs）. In this paper we propose to design an efficient routing protocol for single mobile sink and multiple mobile sink for data gathering in WSN. In this process, a biased random walk method is used to determine the next position of the sink. Then, a rendezvous point selection with splitting tree technique is used to find the optimal data transmission path. If the sink moves within the range of the rendezvous point, it receives the gathered data and if moved out, it selects a relay node from its neighbours to relay packets from rendezvous point to the sink. Proposed algorithm reduces the signal overhead and improves the triangular routing problem. Here the sink acts as a vehicle and collect the data from the sensor. The results show that the proposed model effectively supports sink mobility with low overhead and delay when compared with Intelligent Agent-based Routing protocol （IAR） and also increases the reliability and delivery ratio when the number of sources increases.

The relationship between religious expression and outcomes in online support groups: A partial replication

Shaw and his colleagues [Shaw, B., Han, J., Kim, E., Gustafson, D., Hawkins, R., Cleary, C., et al. (2007). Effects of prayer and religious expression within computer support groups on women with breast cancer. Psycho-oncology, 16(7), 676–687] examined religious expression in breast cancer (BC) online support groups (OSG). Using Pennebaker’s LIWC text analysis to assess religious expression, they found that the more frequent the expression of words related to religion the lower the levels of negative emotions and the higher the levels of health self-efficacy and functional well-being. Our study goal was to replicate their findings. Specifically, we tested their central hypothesis that the percentage of religious words written by members of BC OSG’s are associated with improvement in psychological outcomes. Five BC OSG’s from our previous work [Lieberman, M. A., & Goldstein, B. (2005a). Not all negative emotions are equal: The role of emotional expression in online support groups for women with breast cancer. Psycho-oncology. 15, 160–168; Lieberman, M. A., & Goldstein, B. (2005b). Self-help online: An outcome evaluation of breast cancer bulletin boards. Journal of Health Psychology, 10(6), 855–862] studied 91 participants at baseline and 6 months post. Significant changes in depression and quality of life was found over time. In the current study linear regressions examined the relationship between religious statements and outcomes. The results did not support the hypotheses of a positive relationship between religious expression and positive outcome in both OSG samples. Reviews of studies examining the role of religion in health outcomes report equivocal results on the benefits of religious expression.

Contextual neglect, self-evaluation, and the frog-pond effect.

Social comparisons entail not only information about one’s standing in a social group (intragroup or local comparison) but also information about the standing of the group in comparison to other groups (intergroup or general comparison). In Studies 1–3, the authors explored the relative impact of intergroup and intragroup comparisons on self-evaluations and affect. While intragroup comparison feedback consistently impacted self-evaluations and affect, intergroup comparison information exerted a significant impact only when intragroup comparison information was unavailable. The authors refer to this general tendency as contextual neglect. Studies 4 and 5 showed that contextual neglect is due primarily to the fact that low-level, local comparison information displaces or supersedes the effect of higher level, general comparison data and that people clearly recognize the superior diagnosticity of higher level comparisons while continuing to rely on small, haphazard sample data to evaluate their ability.
