Microspheres with Ultrahigh Holmium Content for Radioablation of Malignancies

Purpose The aim of this study was to develop microspheres with an ultra high holmium content which can be neutron activated for radioablation of malignancies. These microspheres are proposed to be delivered selectively through either intratumoral injections into solid tumors or administered via an intravascularly placed catheter. Methods...

How Crouch Gait Can Dynamically Induce Stiff-Knee Gait

Children with cerebral palsy frequently experience foot dragging and tripping during walking due to a lack of adequate knee flexion in swing (stiff-knee gait). Stiff-knee gait is often accompanied by an overly flexed knee during stance (crouch gait). Studies on stiff-knee gait have mostly focused on excessive knee muscle activity during (pre...

Decision-making on olympic urban development - multi-actor decision support tool

Subject of study is the possible organisation of the Olympic Games of 2028 in the Netherlands, as seen from an urban development viewpoint. The project focuses on the decision-making process in the initiative phase. Aim of the project is the development of a decision support tool for the complex, interdiscicplinary decision-making process wich...

Crawling and Detecting Community Structure in Online Social Networks using Local Information

As Online Social Networks (OSNs) become an intensive sub- ject of research for example in computer science, networking, social sci- ences etc., a growing need for valid and useful datasets is present. The time taken to crawl the network is however introducing a bias which should be minimized. Usual ways of addressing this problem are sampling...

Digital holographic microscopy applied to measurement of a flow in a T-shaped micromixer

In this paper, we describe measurements of a three-dimensional (3D) flow in a T-shaped micromixer by means of digital holographic microscopy. Imaging tracer particles in a microscopic flow with conventional microscopy is accompanied by a small depth-of-field, which hinders true volumetric flow measurements. In holographic microscopy, the depth...

Effects of oxygen and acetoin on fermentation in yeasts

On the existence of a negative pasteur effect in yeasts classified in the genus Brettanomyces Kufferath et van Laer

Even at a mere glance at the extensive literature on the influence of elementary molecular oxygen on the alcoholic fermentation in living yeast cells and various yeast preparations it is evident that so far most works have been concerned with the inhibiting effect produced by this gas on the rate and extent of the process mentioned. Particularly...
