If your doctor, or the doctor of someone you know, is still suggesting exercise therapy for CFS or fatigue in general, that recommendation has now officially had peer review label it

Outdated and misleading content; review unsuitable for clinical decisions

New publication on NO₂ amount fraction measurement using #FTIR. Our approach allowed us to to quantify impurities like N₂O and nitric acid. The focus was on exhaust emission using #PEMS.

Preparándome para la Conferencia Europea de Aerosoles. Esta vez presentaré un poster sobre calibración de conteo de partículas por sistemas #PEMS, los cuales se usan para medir el escape de los carros en condiciones reales de conducción 🚗 💨

Today was all about conservation of energy so I could gradually increase my ride distance without aggravating my #LongCovid. But I managed a 40 mile ride and even managed a very short section at my old pace. Admittedly I had to cut 20 miles off what would have been my usual route, but I’m happy with what I managed. Hopefully because I spent most of my time in zone one/two I’ll not have the terrible #PEMS over the next few days. #Bianchi #OltreXR4

Report: Summary report on the current state-of-the-art of Exhaust Flow Meter (EFM) calibration procedures, including (i) its associated uncertainty for relevant carrier gases and (ii) its relation to on-road emission tests

This report follows from a literature investigation into the current state-of-the-art of PEMS EFM SI-traceable calibration procedures.

Glad to collaborate with colleagues at VSL, who are developing reliable #NO2 gas standards for calibrating #PEMS instruments. #Metrology for a cleaner air.

VSL develops gas standards for Portable Emission Measurement System (PEMS) | Vsl.nl

European legislation sets stringent limits on nitrogen oxides (NOx) and fine particle number (PN) emitted from vehicle exhausts as both are a major source of air pollution and hazardous to human health.

🚗 ⏹️ The MetroPEMS project will address metrological challenges of vehicle exhaust emission quantification. Get to know more in our first stakeholder workshop.

Standards for cleaner car emissions will require traceable methods for #PEMS. The MetroPEMS will develop new standards and calibration procedures for NOx, particle number and exhaust flow. Details are available in the Publishable Summary, now available for download.
