Theranostic Microbubbles with Homogeneous Ligand Distribution for Higher Binding Efficacy

Phospholipid-coated targeted microbubbles are used for ultrasound molecular imaging and locally enhanced drug delivery, with the binding efficacy being an important trait. The use of organic solvent in microbubble production makes the difference between a heterogeneous or homogeneous ligand distribution. This study demonstrates the effect of...

T-Minus engineering: A company in rocketry

The idea started when a group of students from Delft Aerospace Rocket Engineering were sitting at the breakfast table of the Esrange launch base canteen, in the far north of Sweden. It was the day after the successful launch of the self-built Stratos rocket, that broke the European altitude record for amateur rockets. “This is what we love to do...

Stratos II: Halfway to space; the next step in reaching space by a student-built rocket

On top of the world; internship at Esrange Space Center

Low-mobility transport of coarse-grained bed material under waves and currents

The Paintal (1967) formula can be used to estimate transport rates of coarse-grained bed material (such as stones from a bed protection) under low hydraulic loads just above the threshold of motion; the application however is limited to steady currents. This paper presents research aimed at extending the range of application to a combination of...

Scour around an offshore windturbine

During the construction of the first Dutch offshore wind farm prototype measurements were performed. These measurements were aimed to monitor the behaviour of the granular filter layer of the scour protection around the mono-piles upon which the wind turbines are founded. These measurements were compared to scale model test results and...

Experimental research on the stability of armour and secondary layer in a single layered Tetrapod breakwater

Physical model tests were done on an armour of Tetrapods, placed in a single layer. The objective of the investigations was to study the stability of the secondary layer, and to see if the material of this secondary layer could be washed out through the single layer of Tetrapods. It was concluded that secondary armour is not washed out through...

Influence of the density of placement on the stability of armour layers on breakwaters

Studies on the stability of the amour layer (d’Angremond et. al. [1999] revealed the importance of density of placement. The current research focuses on the influence of the density of placement on the stability of cubes in a double armour layer and tetrapods and rocks in a single armour layer. The experiments were performed in the Laboratory of...

Comparison of several alternative toside designs, based on a F3-FB-1 wellhead production platform concept

Analyse brandingsstroommetingen nabij Joossesweg (Westkapelle)

In de periode maart tot april 1985 heeft de Adviesdienst Vlissingen enige brandingsstroommetingen uitgevoerd voor de kust van Walcheren ter hoogte van Joossesweg (nabij Westkapelle). Het doel van het meetonderzoek is het verkrijgen van meer inzicht in de veranderingen die optreden op een gesuppleerd strand ten gevolge van stroom en golven. Met...

Hydro-morphological study Douro estuary part 9: Hydro-morphological mathematical model

As a continuation of the initial study on the morphology of the Douro mouth, performed by Hydronamic in 1982, the Administracao dos Portos do Douro e Leixoes commisioned Hydronamic bv to construct a mathematical hydro-morphological model of the Douro mouth. This second part of the morphological study of the Douro mouth is divided into three...
