World Water Policy, Volume 12, Issue 4, November 2026.ABSTRACT This paper describes and analyzes recharge practices in Bács‐Kiskun County, Hungary, within what can be categorized as the farmer domain. Such locally embedded aquifer recharge practices remain underexplored in Hungary. Current research and funding largely focus on large‐scale Managed Aquifer Recharge (MAR) interventions emphasizing intended ...

World Water Policy, Volume 12, Issue 4, November 2026.ABSTRACT This article examines how renewable‐energy expansion is changing water–energy bargaining among Iran, Iraq, and Türkiye in the Tigris–Euphrates basin. Much of the existing literature on transboundary water politics focuses on territorial control, upstream–downstream power asymmetries, legal rules, and hydro‐hegemony but gives less attention to ...

Policy Studies Journal, Volume 54, Issue 4, November 2026.ABSTRACT This paper examines how governments navigate policy legitimacy during crises through three distinct discursive processes: legitimization, delegitimization, and blame avoidance. Using a sequential mixed‐methods design, the study analyzes Denmark's decision to cull all mink during the COVID‐19 pandemic. The quantitative analysis of 947 newspaper

, 2016 埋深浅、油层破裂压力高或EOR过程中垂向地应力减小的油层水力压裂后容易形成水平裂缝,为此基于模拟垂直裂缝的嵌入裂缝模型,提出了一种能够高效处理水平裂缝的油藏数值模拟方法,准确模拟了水平裂缝对油层开采状况的影响。采用规则网格单独剖分油藏基质,根据水平裂缝与油藏网格的多边形相交面划分非规则裂缝网格,通过定义非相邻网格连接记录裂缝网格与基质网格、井之间的连接关系。基质与裂缝耦合的流体流动方程离散后,建立了带有加边七对角稀疏系数矩阵的三维油藏基质与裂缝系统数值模拟模型 ...

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.

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Biomass‐based hydrogels are widely regarded as ideal substrates for self‐powered wearable sensors. However, the practical applications of hydrogels are commonly limited by their inherent low strength and toughness, which restrict their capacity to withstand repeated stretching, bending and other mechanical loads arising from human motion in ...

, 2017 天然气水合物是一种重要的非常规能源,但水合物开采出砂问题成为制约其走向商业化开发的关键因素。南海北部陆坡是我国天然气水合物的重要赋存区,其水合物主要以分散状弱胶结方式赋存,研究其出砂问题显得极为迫切。研究表明储层出砂的根本原因是储层介质强度降低,而水合物储层介质强度受到水合物胶结模式、水合物饱和度、孔隙流体压力、流速及生产压差等影响。本文在对比分析天然气水合物储层出砂与常规油气藏出砂特征的基础上,总结了弱胶结疏松砂岩油藏出砂研究方法 ...

Scientists’ warning on the global destruction of rock outcrop ecosystems
Conservation Biology, Volume 40, Issue 5, October 2026.Abstract Rock outcrops are geological formations that harbor a highly specialized biota adapted to harsh environmental conditions that differ from their surrounding landscapes. They are globally distributed, especially in old, highly weathered landscapes, and can function as habitat islands containing high levels of endemism and distinct evolutionary ...

Gongye shui chuli, 2023 采出水回注是国内处理气田采出水的有效手段，但是，由于不同工艺处理效果存在差异，导致采出水中未被处理的部分悬浮物对回注地层造成不同程度的堵塞伤害。运用激光粒度衍射分析技术、室内物理流动模拟实验结合核磁共振技术，开展采出水回注室内模拟实验，定量评价采出水悬浮物对岩心样品的伤害程度，明确不同工艺处理效果，揭示回注地层堵塞伤害机理。实验结果表明，气田采出水悬浮物粒径尺度是影响回注地层堵塞程度的主控因素，发生堵塞伤害的悬浮物粒径主要分布在7.65~52.62 μm；采用“破乳+油水分离+沉降除油+气浮+旋流分离 ...
