International Journal of Applied Linguistics, Volume 36, Issue 1, Page 522-539, February 2026.ABSTRACT This paper examines the features of metadiscourse across different teacher moves in university linguistics classroom discourse and the teaching strategies reflected in its use. The results reveal that teachers employ diverse metadiscourse during classroom interactions to support student reasoning.

, 2009 本研究基于空间实验资源限制条件下,为满足空间细胞模式化生长以及细胞聚集和粘附实验的需求,发展了新型的空间细胞生物力学实验装置。微重力细胞生物学实验一直面临如何将浮力对流消失引起的细胞培养传质条件改变的影响与细胞对重力的直接感应有效区分开来的问题。在这种情况下,控制和量化实验条件参数对于不同重力条件下的实验结果对比将是至关重要的。本研究基于表面微模式化及微流道技术研制了新型空间细胞培养器,通过对实验流道内流场及物质输运的相关力学分析,计算了细胞代谢对氧、葡萄糖等营养物质的消耗速率 ...

A new beef: An analysis of discourse coalitions in the nascent cellular agriculture policy subsystem
Review of Policy Research, Volume 42, Issue 6, Page 1404-1427, November 2025.Abstract A robust approach to examining the nature and influence of coalitions in the policy process is the Advocacy Coalition Framework (ACF), which is especially useful to study policy issues fraught with scientific and technical controversy. Yet, important gaps exist in ACF literature regarding nascent policy subsystems. Consequently, there is scant

Dianci bileiqi, 2020 避雷器瓷外套是保护避雷器不受外界环境影响的一道防线,瓷外套保持绝缘性能良好对避雷器的安全运行具有重要意义。利用有限元法建立了避雷器三维模型,研究了晴天和雨天、工频电压和操作过电压下避雷器顶部螺栓对瓷外套电场的影响,并分析了现场避雷器的疑似放电痕迹产生原因。结果表明,螺栓过长使得空气间隙平均电场强度增大,遭受操作过电压时很可能发生击穿;淋雨状态下,螺栓形成水柱后,螺栓和伞裙空气间隙击穿很可能发生击穿;伞裙形成水柱后,伞裙间空气间隙也很可能发生击穿,形成放电痕迹。因此,在运行中应避免避雷器顶部法兰螺栓过长 ...

Conservation Biology, Volume 39, Issue 5, October 2025.Abstract Primates, 69% of which are threatened with extinction, are the third most specious order of mammals. We used primates as model taxa to examine the umbrella effects of primates on ecosystem services and the protection of other vertebrates and seed plants in Yunnan Province, China.
