Review of Policy Research, Volume 43, Issue 6, November 2026.ABSTRACT Nature conservation conflicts increasingly extend beyond ecological objectives to disputes over decision‐making legitimacy, institutional authority, and competing understandings of landscape and expertise. This article examines the conflict over the proposed designation of Křivoklátsko as a national park in the Czech Republic between 2021 and ...

Jianzhu Gangjiegou Jinzhan, 2016 H形钢悬臂柱柱脚焊缝的疲劳性能对钢柱疲劳寿命起控制作用,应用热点应力的表面外推法,通过建立数值计算模型,对弯矩、扭矩和弯扭共同作用下柱脚焊缝热点应力进行了分析。选取翼缘与底板厚度比(t1/t2)、翼缘和腹板厚度比(t1/t3)、腹板厚度(t3)与型钢截面高度(h)作为影响因素,对热点应力集中系数SCFhs进行参数分析。分析结果表明,其它条件不变的情况下,弯矩作用下的热点应力集中系数SCFmhs随着(t1/t3)和(t3)的增大而减小,但与(t1/t2)关系不大,h增加可导致SCFhs增大,建议取为1 ...

应力增量触发断层岩体能量释放模拟与地震成因探讨—以龙门山断裂带为例
Dizhen xuebao, 2019 本文以龙门山断裂带为背景，基于岩体应变能基本理论，使用FLAC软件模拟地震能量源和能量释放形式，计算结果显示：在0.01 MPa水平应力增量作用下，龙门山断裂带及附近区域可释放的应变能约为3.24×1013 J；使得断层面之间发生滑移，克服断层面滑动摩擦所需消耗的能量约为2.10×1013 J；岩体在重力方向上产生位移，克服重力做功所消耗的能量约为1.14×1013 J。由此可推断：在一定区域内，应力触发释放能量值与克服断层面滑动摩擦和克服重力做功所消耗的能量之和大致相当 ...

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT The use of Ti6Al4V alloy in dental implantation is constrained by its high elastic modulus and biological inertness, which lead to delayed osseointegration and a high failure risk. Additionally, its chemical incompatibility with hydroxyapatite (HA) impedes the development of stable bioactive composites.

Shuitu Baochi Xuebao, 2018 坡面水流的输沙能力是影响土壤侵蚀过程的重要参数之一，加强坡面集中水流输沙能力的研究有助于深入理解集中流发生机理，并为防治集中流侵蚀发生提供科学依据。采用室内集中流放水冲刷试验，以黄土高原典型黄绵土为研究对象，研究了集中流输沙能力与放水流量和坡度以及与单宽流量和坡度之间的关系，同时对集中流水力参数和输沙能力的相应关系进行了研究。结果表明:集中流输沙能力随着坡度和放水流量的增加而增加。多元统计分析建立输沙能力与坡度和放水流量之间的幂函数关系发现坡度指标对输沙能力相对放水流量影响更大，而在坡度和单宽流量作用下，

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Lithium‐rich manganese‐based cathodes (LRM) deliver high discharge capacities beyond 250 mAh g−1, but their practical deployment is restricted by irreversible oxygen redox, structural reconstruction, sluggish kinetics and unstable cathode‐electrolyte interfaces (CEI). Here, we develop a colloid‐assisted anchoring‐diffusion engineering strategy
