Published: July 2010

High-quality Dyson imaging spectrometers are designed by applying a telecentric condition for off-axis image points. By imposing this condition for two different wavelengths, designs presenting low aberrations for the whole spectral range of the system are obtained. A UV-TO-NIR fast design (f/1.5) exhibiting excellent optical performance is presented.

Selective catalytic oxidation (SCO) of NH to N is one of the most effective methods used to eliminate NH emissions. However, achieving high conversion over a wide operating temperature range while avoiding over-oxidation to NO remains a significant challenge. Here, we report a bi-metallic surficial catalyst (PtCuO/AlO) with improved Pt atom efficiency that overcomes the limitations of current catalysts.

Slowly getting there: a review of country experience on estimating emissions and removals from forest degradation.

Carbon Balance Manag

November 2024

Food and Agriculture Organization of the United Nations, Viale Delle Terme Di Caracalla, 00153, Rome, RM, Italy.

Estimating emissions and removals from forest degradation is important, yet challenging, for many countries. This paper reports results from analysis of country reporting (to the United Nations Framework Convention on Climate Change and also to several climate finance initiatives) and key take-aways from a south-south exchange workshop among 17 countries with forest mitigation programmes. During the workshop discussions it became clear that, where forest degradation is a major source of emissions, governments want to include it when reporting on their mitigation efforts.

Article Synopsis
  • Real-world collision data reconstruction helps to understand injury biomechanics and identify injury thresholds, but it often suffers from uncertainty in parameters like impact speed and pedestrian characteristics.
  • A study was conducted using six pedestrian-car collision cases from the GB Road Accident In-Depth Studies (RAIDS) database, considering variations in input parameters to analyze the effects on head kinematic metrics related to injury risk.
  • The analysis revealed that input uncertainty differently affected the initial head-vehicle impact and the subsequent head-ground impact, and real-world evidence helped constrain the most realistic scenarios for injury prediction.

Article Synopsis
  • Radiological evaluations of the cervicothoracic junction in horses with neck-related clinical signs haven't been thoroughly analyzed before this study.
  • The research compared 127 control horses to 96 horses showing symptoms like neck pain, forelimb lameness, and proprioceptive ataxia, using standardized clinical and radiological methods.
  • Findings indicated that horses with clinical signs had a higher likelihood of severe articular process issues and spondylolisthesis at C7-T1, and showed various radiological abnormalities that stress the need for detailed assessments in symptomatic horses.

Spatially resolved photoluminescence (PL) and electroluminescence (EL) imaging technologies play a crucial role in evaluating the performance and stability of photovoltaic devices. However, their application in perovskite devices presents unique challenges. In this study, we report a discrepancy between the electrical performance of perovskite solar modules (PSMs) and the EL images.
