Trends and anomalies in the coherence of the Southern Polar Vortex: A 26 year meta-study [PDF]

Scientific Reports
The coherence and annual dissipation of the Southern Polar Vortex (SPV) are examined for anomalous behavior and trends, using data from the past 26 years, on four different levels in the Earth’s atmosphere. In order to quantify the SPV’s coherence in the

Lower spinal postural variability during laptop-work in subjects with cervicogenic headache compared to healthy controls

Scientific Reports, 2021
Spinal postural variability (SPV) is a prerequisite to prevent musculoskeletal complaints during functional tasks. Our objective was to evaluate SPV in cervicogenic headache (CeH) since CeH is characterized by such complaints.

Performance evaluation of solar panels under different dust accumulation conditions using thermography: focusing on PV temperature variation

Materials for Renewable and Sustainable Energy, 2023
Degradation performance of photovoltaic modules (SPV) by real conditions has become increasingly problematic. In dusty areas, dust accumulation is one of the main concerns that may cause a significant determination of SPV efficiency. In the current study,

Surface photovoltage characterisation of metal halide perovskite on crystalline silicon using Kelvin probe force microscopy and metal-insulator-semiconductor configuration

EPJ Photovoltaics, 2022
In this study we analysed halide perovskite films deposited directly on crystalline silicon by means of two set-ups using different operating modes of the surface photovoltage (SPV) methods, i.e., the Kelvin probe force microscopy (KPFM) and the metal ...
