Analysis of the main innovations in directive 2015/1513 on renewable energy

This article assesses the main innovations in the newly adopted Directive 2015/1513 on renewable energy and biofuels in the EU transport sector. It analyses the strengths and weaknesses of this legal framework and reflects on possible future elaborations of the EU approach to renewable energy and sustainable biofuels in the transport sector. These developments must be in balance with the productio

Trace Metals in the St. Louis Aerosol

The elemental composition of the St. Louis aerosol has been investigated at rooftop sites in south and central locations in the city as part of the August, 1973 field season of the Regional Air Pollution Study of the U.S. Environmental Protection Agency. Sampling by 5-stage cascade impactor with backup filter permits analysis by proton-induced x-ray emission (PIXE) of size fractions of aerodynamic

Measurement of the Acoustic properties of resilient, statically tensile loaded devices in light weight structures: A measurement method and statistical analysis

Resilient devices are commonly used in lightweight structures to decrease sound transmission in a broad frequency band. Applications of such devices may be found in e.g. resilient mounted ceilings in aeroplanes, ships and buildings. A measurement method to characterise the frequency dependency of the transfer stiffness and the input stiffness of the resilient device is presented. The mechanical ch
