The Problem With Problem Load: Reconceptualizing Load in the Multiple Streams Framework
Review of Policy Research, Volume 43, Issue 6, November 2026.ABSTRACT What happens when policymaking systems buckle under pressure, disrupting consensus and stalling decision‐making? Drawing on the Multiple Streams Framework, we show that the existing concept capturing this stress, Problem Load, has been both misinterpreted and overstretched.

Zhongguo shiyan zhenduanxue, 2012 目的探讨呼出气冷凝液（EBC）收集方式,EBC保存时间与吸烟等对EBC内pH值、一氧化氮（NO）、过氧化氢（H2O2）测定结果的影响,从而确定EBC收集的条件,提高EBC内物质检测结果准确性。方法应用自行研制的EBC收集器对20名健康受试者进行EBC的收集。收集的受试者分别采用不同呼吸方式、不同冷却温度、不同通气管等进行样本收集。EBC的pH值测定应用pH仪,NO和H2O2测定分别采用化学分析法进行测定。结果 pH值检测主要受到EBC采集时呼吸方式的影响,NO检测受到EBC采集时呼吸方式 ...

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Aqueous Zn‐ion batteries (AZIBs) are expected to become one of the most promising candidates for large‐scale energy storage, but are impeded by uncontrollable dendrite growth and parasitic reactions. In this study, we propose a simple mechanical shot‐peening (SP) approach for restructuring commercial Zn foils into highly exposed (002)‐textured

Gongye shui chuli, 2008 分别用沉积法和鼓泡法测定了不同钙含量的自来水样和标准水样中同剂量、同一水处理剂的阻垢性能。结果表明,鼓泡法适用于高钙水样和低钙水样中水处理阻垢性能的测定；在测定水处理剂的阻垢性能时,应采用和实际水样钙离子含量相似的标准水样,才能准确地反映出其实际应用时的阻垢性能。

Ultrasonic Vibration Assisted Laser Processing: A Hybrid Paradigm for Extreme Surface Enhancement
Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Traditional laser processing techniques offer many advantages, but they often encounter limitations such as heat‐affected zones, recast layers, residual tensile stresses, and poor surface finish. The integration of ultrasonic vibration (UV) presents a promising hybrid approach to overcome these challenges by introducing beneficial effects like

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT To achieve high‐value utilization of spent catalysts, we recovered copper (Cu) from Cu‐bearing spent catalysts via acid‐base leaching to fabricate CuO and systematically studied how calcination temperature affects their microstructure and humidity‐sensing performance. Characterizations show that CuO‐500 (calcined at 500°C) has a large specific

TA10 Titanium Alloy in HCl Solution: W‐Influenced Corrosion and Passivation Film Evolution
Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT This work investigated the evolution of passive films of Ti–0.3Mo–0.8Ni (TMN) in 5 mol L−1 HCl and studied the influence of W on the anti‐corrosion properties of TMN. The intermittent electrochemical impedance spectroscopy test results showed that when TMN entered 5 mol L−1 HCl solution, the stability of the passive film first became stronger ...
