De emissies van stikstofoxiden (NO- NO2) en deeltjes (PM) vanuit de binnenvaart leveren een belangrijke bijdrage aan luchtverontreiniging boven Nederland. Tot nu toe is de verspreiding van die luchtverontreiniging rondom vaarwegen op eenzelfde manier berekend als voor wegverkeer. Echter, het grote vermogen van de motoren in schepen kan er in...

Op verzoek van het RIVM (en in opdracht van het Ministerie van Infrastructuur en Milieu) is een oriënterend onderzoek uitgevoerd naar de concentraties van ultrafijn stof (UFP) in de omgeving van Schiphol. ECN heeft deze verkennende metingen gecoördineerd. Aan de meetcampagne hebben TNO, VITO en RIVM meegewerkt. Gemeten is op...

Het kan voor mensen die werkloos zijn en met name voor mensen met een laag opleidingsniveau, gebrek aan werkervaring en/of belemmeringen van psychische, lichamelijke en/of verstandelijke aard lastig zijn om een goed beeld te krijgen van beroepen die bij hen passen. Virtual Reality (VR) biedt de mogelijkheid om werkzoekenden op een laagdrempelige...

Assessment of the level of sea salt in PM10 in the Netherlands Effect on yearly average and exceedance days The European air quality directive allows the subtraction of natural contributions from the levels of PM10. In 2005 a regulation for sea salt was implemented in Dutch legislation. The sea salt levels in this regulation now appear to be too...

1. Fainting is a common phenomenon in young subjects, but the final events before the actual faint are not well known. The aim of the present study was to study the inter-individual variability of haemodynamic events associated with near-fainting in children and teenagers. 2. Sixty-eight healthy subjects (aged 6-16 years) performed a 70°tilt-up...

Portapres is a noninvasive, beat-to-beat finger blood pressure (BP) monitor that has been shown to accurately estimate 24-hour intra-arterial BP at normal and high BPs. However, no information is available on the ability of this device to accurately track ambulatory BP variability. In 20 ambulatory normotensive and hypertensive subjects, we...

Pressure-volume (p-V) relationships of a segment of the forearm circulation have been measured in nine male healthy subjects. Forearm volume was measured using electrical impedance plethysmography, arterial transmural pressure by subtracting mean arterial pressure measured contralaterally in a finger from the pressure in a cuff placed over the...

When infrastructures projects are evaluated, it is not only important to evaluate them with models that represent the average daily situation, but also to evaluate them in case of irregular situations like incidents. This becomes especially relevant when various project alternatives are expected to show significantly different scores in case of...

In the clinic, blood pressure is measured almost exclusively using non- invasive intermittent techniques, of which the auscultatory (Riva- Rocci/Korotkoff, RRK) and the computerized oscillometric method are most often used. However, both methods only provide a momentary value. In addition, the accuracy is hampered by phenomena such as cuff...

Twenty-one years ago, in 1967, lecturer dr, Jan Peñáz submitted a patent description of a method to measure indirectly the full arterial pressure waveform in a finger using a volume clamp technique, and at the lOth Conference on Medical and Biological Engineering at Dresden in 1973, he actually demonstrated a device and published a one-page...

The most fallible component of blood pressure measurement is the human observer. The traditional technique of measuring blood pressure does not allow the result of the measurement to be checked by independent observers, thereby leaving the method open to bias. In the Sphygmocorder, several components used to measure blood pressure have been...

The proper understanding of the cardiovascular mechanisms involved in complaints of short-lasting dizziness and the evaluation of unexplained recurrent syncope requires continuous monitoring of cardiac stroke volume (SV) in addition to blood pressure and heart rate. The primary aim of the present study was to evaluate a pulse wave analysis...

Objectives We set out to determine the effect of sublingual nitroglycerin (NTG), as used during routine tilt testing in patients with unexplained syncope, on hemodynamic characteristics and baroreflex control of heart rate (HR) and systemic vascular resistance (SVR). Background Nitroglycerin is used in tilt testing to elicit a vasovagal response...
