International Journal of Urban and Regional Research, Volume 50, Issue 1, Page 191-220, January 2026.Abstract Henry George advocated for capturing land value increases for public ends. The active approach of public authorities organizing and financing land development can help capture higher land value increases, as Hartman and Spit indicate. However, this approach hardly happens in developing countries, where the coalition of private developers and ...

Integrative Conservation, Volume 4, Issue 4, Page 652-664, December 2025.We profiled nutritional and physiological markers in captive sifakas, endangered primates from Madagascar, managed in expansive, non‐native forest enclosures. Variation in many markers reflects freely foraged diets and the energy required to maintain homeostasis under more naturalistic conditions.

Predictions of southern migration timing in coastal sharks under future ocean warming
Conservation Biology, Volume 39, Issue 6, December 2025.Abstract Projected redistribution of marine species due to ocean warming may undermine current conservation efforts. Yet, there have been few studies on how ocean warming may alter migration timing. Across 5 years of acoustic telemetry data (2018–2022), we determined environmental drivers of southward migration timing for 6 migratory shark species from

Gaoya dianqi, 2023 全封闭组合电器设备作为一种当今现场广为使用的电气设备，常因导体接触不良等故障，导致其温度不断上升，从而引发事故发生。文中对GIS中盆式绝缘子导体热点分布情况进行分析，将荧光光纤温度传感器植入盆式绝缘子内部，直接测量导体温度。并对内置光纤传感系统的电场分布和加入光纤系统后的电场分布进行了分析并通过实验验证，明确使用光纤传感系统的安全性。并通过GIS温升试验对比光纤测温与内置热电偶测温，说明光纤测温的有效性。

Global Change Biology, Volume 31, Issue 11, November 2025.This study assessed the potential impacts of climate and land‐use change on soil fungal diversity across four North American biomes. We found that climate change typically caused both diversity losses and gains, particularly in coniferous forests and among arbuscular mycorrhizal fungi, whereas land‐use change mainly reduced diversity, especially in ...

Jianzhu Gangjiegou Jinzhan, 2016 通过有限元方法研究火灾下无防火保护蜂窝钢梁孔间腹板屈曲性能及屈曲温度。首先采用有限元传热分析,获得标准火灾下无防火保护蜂窝梁不同受火时刻的三维有限元温度分析结果,然后采用有限元受力分析确定三维有限元温度分析结果下蜂窝梁孔间腹板的受力性能和屈曲温度。传热分布结果表明,开孔后增加了孔洞周边厚度方向上腹板与空气间的热量交换,使得腹板升温速率明显大于翼缘。火灾下结构受力分析结果表明,由于钢材的力学性能随温度升高而降低,而且中心腹板升温速率快使蜂窝梁更易发生孔间腹板屈曲破坏 ...

Zhejiang Daxue xuebao. Lixue ban, 2018 青藏高原和印度洋均对我国气候有重要影响，研究高原和印度洋的热力状况及其耦合关系对全面了解我国的天气现象具有重要意义.利用1981 — 2010年(30 a)欧洲中心ERA-interim的青藏高原和印度洋温度资料，以及NCEP/NCAR的垂直速度和风速资料，分析了青藏高原地气温差和印度洋海气温差的特征及其相互影响.结果表明，高原冬、夏季地气温差有所区别：冬季地气温差呈东北-西南向的带状分布，在高原中部、西南边界喜马拉雅山脉地区和东南边界出现了较大的负值中心，其他地区均为正值；夏季地气温差均为正值 ...

Integrative Conservation, Volume 4, Issue 3, Page 430-441, September 2025.Our study identifies southern China, including mountainous regions and islands, as key areas rich in phylogenetic diversity, and phylogenetic endemism of lizards that are currently under‐protected. Current protected areas however do not adequately cover regions that are critical for preserving the evolutionary history of lizards.

Gaoya dianqi, 2018 为实现油浸式电力变压器绕组运行温度的分布式测量,及早发现绕组异常温升等问题,文中提出了一种基于Raman光时域反射计（ROTDR）的变压器绕组温度测量方法。该方法通过在变压器绕组中预埋分布式光纤,并依据拉曼散射原理来直接测量绕组温度。设计并研制了敷设分布式光纤的电磁线和绕组模型,并根据测量要求对电磁线结构和绕组绕制工艺进行了改进,利用分布式光纤测温系统对敷设分布式光纤的电磁线温度传感性能和绕组模型进行了试验。试验结果表明:基于该方法的温度测量误差≤2℃,满足变压器绕组温度测量的要求 ...
