The catalytic conversion of oleic acid to aromatics (benzene, toluene, and xylenes, BTX) over a granular H-ZSM-5/Al2O3 catalyst (ϕ 1.2–1.8 mm, 10 g loading) was investigated in a continuous bench-scale fixed-bed reactor (10 g oleic acid h–1). A peak carbon yield of aromatics of 27.4% was obtained at …

In a long-term project, together with Courage, we are investigating whether it is possible to determine volatile fatty acids, methane or acetone in the air blown from dairy cows. These substances are associated with health and digestion of the cow. We are working on a sensor together with tech partners …

In face of climate change and urbanization, the need for thermally comfortable outdoor urban spaces is increasing. In the design of the thermally comfortable urban spaces and decision making about interventions that enhance thermal comfort, scientists and professionals that work for cities use meteorological …

"This publication, leaded by the National University of Singapore School of Design and Environment, presents the research by design results of four consecutive years in four different countries (China, Philippines, Indonesia and Thailand) responding to the current challenge of building more resilient …

This chapter examines how an adequate Internal Compliance Program (ICP) for the Royal Netherlands Airforce (RNLAF) was developed. In order to create an adequate ICP, it is essential to determine which legal and other aspects should be incorporated in the ICP framework. To deduct these relevant aspects …

Passenger flow management is an important issue at many airports around the world. There are high concentrations of passengers arriving and leaving the airport in waves of large volumes in short periods, particularly in big hubs. This might cause congestion in some locations depending on the layout of …

Airport operations are undergoing significant change, having to meet pandemic requirements in addition to intrinsic security requirements. Although air traffic has declined massively, airports are still the critical hubs of the air transport network. The new restrictions due to the COVID-19 pandemic …

Paris Charles de Gaulle Airport was the second European airport in terms of traffic in 2019, having transported 76.2 million passengers. Its large infrastructures include four runways, a large taxiway network, and 298 aircraft parking stands (131 contact) among three terminals. With the current pandemic …

According to the International Civil Aviation Organization, the world aviation air traffic has grown by an average yearly rate of 5% over the last thirty years, until the devastating downturn brought on by the COVID crisis of 2020. Regardless of the current situation, there are still a number of issues …
