City Diplomacy as a Green Strategy? International Sister City Partnerships and Urban Decarbonization

open access: yesSustainable Development, EarlyView.
ABSTRACT The establishment of international sister city partnerships (ISCPs) has expanded since the postwar era, developing from cultural exchanges into strategic diplomatic channels for sustainable development. While their socioeconomic benefits are well‐documented, their potential as instruments for global environmental governance and urban ...

Deflection‐based assessment of residual prestress in simply‐supported bridges accounting for creep variability

open access: yesStructural Concrete, EarlyView.
Abstract Several test methods have been proposed in the literature for measuring the level of residual prestress, most of them involving either semi‐ or fully destructive techniques for local measurements which could be highly sensitive to boundary conditions and execution details.

How weather got its words: a history of meteorological English – Part 2: the scientific age and beyond

open access: yesWeather, EarlyView.
The English language is a gargantuan, gluttonous beast. It has become extraordinary in its powers of assimilation – such that we rarely consider the origins of the words we use. In this paper, we will shed light on these origins, including the Pontic–Caspian steppe, the British Empire and, of course, a TV show.

Research on Self‐Identification Technology of Zero‐Value Insulators in Distribution Lines Based on Electroluminescence Effect

open access: yesHigh Voltage, EarlyView.
ABSTRACT To address the issue of low detection accuracy for zero‐value insulators in distribution lines, this study proposes a novel method for detecting these insulators based on the electroluminescence effect. Through theoretical analysis and experimentation, it was found that the luminescence intensity of ZnS:Cu electroluminescent material varies ...

Study on the Coupled Effects of High‐Speed Airflow and Charged Sand on Power‐Frequency Discharge Characteristics of Conductor–Tower Gaps in Strong Wind–Sand Environments

open access: yesHigh Voltage, EarlyView.
ABSTRACT Strong wind–sand weather in Xinjiang threatens power grid safety by increasing transmission line tripping risks. Existing studies focus on sand polarization but neglect the coupled influence of high‐speed airflow and charged sand on gap discharge characteristics.

Wave‐Velocity‐Based Temperature Monitoring Applied to Underground Power Cables in Medium‐Voltage Networks—Discrimination of Individual Cable Temperatures in a Distribution Grid

open access: yesHigh Voltage, EarlyView.
ABSTRACT The thermal state of underground power cables can be monitored based on the temperature dependency of the dielectric permittivity of the insulation material. The resulting temperature‐dependent wave velocity is used as a thermometric property. To this end, the signal propagation time along a cable of an injected signal is determined.

Ion‐Flow Field Modelling of ± 1100 kV Transmission Lines Under Strong‐Wind Scenarios Using the Multiple Relaxation Time Lattice Boltzmann Method

open access: yesHigh Voltage, EarlyView.
ABSTRACT To solve the ion‐flow field of ultrahigh‐voltage direct current (UHVDC) transmission lines under strong‐wind scenarios, the multiple relaxation time lattice Boltzmann method (MRT‐LBM) is adopted. Compared with previous ion‐flow studies predominantly based on the single relaxation time LBM, the MRT‐LBM framework provides improved numerical ...

Study on the Amplification Factor of Ice‐Shedding Jump Height of Transmission Lines Under Ice–Wind Coupling

open access: yesHigh Voltage, EarlyView.
ABSTRACT Ice accumulation on transmission lines poses a persistent threat to grid stability, yet precise technical guidance for the dynamic response during ice shedding under wind loads remains insufficient. In response to this issue, this study uses C++ to create a calculation program and obtains aerodynamic coefficients of ice‐covered conductors with

Conductivity Analysis and Thermoelectric Behaviour of Larch Standing Trees Under Lightning Currents: Role of Moisture Distribution and Carrier Motion

open access: yesHigh Voltage, EarlyView.
ABSTRACT The direct effects of lightning strikes on forest combustibles form the foundation for predicting lightning‐induced forest fires. Accurate assessment of lightning impact is hindered by limited knowledge of the conduction characteristics of standing larch trees.

Fallow Fields, Falling Incomes: The CAP 2023–2027 Framework in the Italian Cereal Sector Champs en jachère, revenus en baisse : Le cadre de la PAC pour 2023–2027 dans le secteur céréalier italien Brachliegende Felder, sinkende Einkommen: Die GAP 2023–2027 im italienischen Getreidesektor

open access: yesEuroChoices, EarlyView.
Summary Analysis of recent Eurostat data shows a progressive decline in EU cereal production. While cultivated acreage has contracted steadily since 2013, the most severe output reduction occurred during 2022–2024, driving a surge in import volumes. This is mirrored in Italy, exposing systemic vulnerabilities within high‐value agri‐food supply chains ...
