Bubble counter based on photoelectric technique for leakage detection of cryogenic valves

In order to overcome the inconvenience of manual bubble counting, a bubble counter based on photoelectric technique aiming for automatically detecting and measuring minute gas leakage of cryogenic valves is proposed. Experiments have been conducted on a self-built apparatus, testing the performance with different gas inlet strategies （bottom gas-inlet strategy and side gas-inlet strategy） and the influence of gas pipe length （0, 1, 2, 4, 6, 8, 10 m） and leakage rate （around 10, 20, 30, 40 bubbles/min） on first bubble time and bubble rate. A buffer of 110 cm^3 is inserted between leakage source and gas pipe to simulate the downstream cavum adjacent to the valve clack. Based on analyzing the experimental data, experiential parameters have also been summarized to guide leakage detection and measurement for engineering applications. A practical system has already been successfully applied in a cryogenic testing apparatus for cryogenic valves.

Opposite effects of miR-155 in the initial and later stages of lipopolysaccharide (LPS)-induced inflammatory response

Although microRNA-155(miR-155) is considered a pro-inflammatory mediator, cumulative evidence indicates that it also has anti-inflammatory effects in macrophages and dendritic cells. In this study, we identified the dramatic expression changes of more than half of potential miR-155-targeted genes upon lipopolysaccharide(LPS) stimulation; 223 genes were down-regulated and 85 genes were up-regulated, including suppressor of cytokine signaling 1(SOCS1) and transforming growth factor-β-activated kinase 1-binding protein 2(TAB2), two well-known genes involved in miR-155-mediated regulation of the Toll-like receptor 4(TLR4) signaling pathway. We also found that miR-155 acted as an anti-inflammatory mediator in the initial stage of LPS-induced inflammatory response mainly through repressing TAB2 protein translation, and as a proinflammatory mediator by down-regulating SOCS1 in the later stage. Meanwhile, overexpression of TAB2 3' untranslated region(UTR) in macrophages promoted the development of endotoxin tolerance by competing for binding with miR-155, which resulted in an elevated expression level of SOCS1 protein. These findings provide new insights for understanding the regulatory mechanisms in fine-tuning of LPS-induced innate immune response.     

区域协作构建肉羊繁育体系试点之思考

整合地方肉羊产业资源,试点以人工授精技术等现代繁殖技术应用为基础,建立繁育体系架构,将专业人员和养殖经营者群体结合,分别执行复杂程度不同的上下游技术措施,开展以肉羊杂种优势利用为主的区域协作,取得符合不同季节发情调控和妊娠的一般应用效果,分娩的羔羊具有明显杂种或本品种外貌和生长发育特征.以此分析我国农区羊业小规模养殖和散在分布特点决定了区域协作是建立合理繁育体系的选择.在技术上提出良好的繁育效果需要现代繁殖技术与传统繁殖方式结合,在实施路径上强调政府引导和基于数据监控机制的重要性,构建以养殖经营主体为基础的协会主导管理体系.旨在为解决羊业生产所面临繁育体系缺乏活力和良种利用率低等问题,以期为推进羊产业发展提供思路.     

社会创业视角下的社会价值创造研究与展望

社会创业是一种可持续创造价值的方式,其实质就是创造社会价值的完整过程.社会价值可以看作是组织将各项资源进行整合并投入各种要素、开展运营过程和实施最优化系统组合后,为个人、团队或整个社会生活所产生的影响与改善部分.结合现有研究中关于能力理论、改善社会福祉的需求和社会创业者个人特质等流派观点,对社会价值的内涵进行全面梳理,对社会价值评估方法进行总结.从商业模式、影响因素和创业过程模式三个角度分析,发现厘清概念、构建整合性分析框架以及数字化变革背景下的实证研究是未来重点的研究方向.
