ABSTRACT
The dynamic wetting behaviour and the mobility of droplets on fibres is a very important factor in coating processes, textile fabrication, in self-cleaning processes and in the filtration of fluids. In principal, filter regeneration depends on the mobility of the droplets on the fibre surface. Mobile droplets tend to coalesce which greatly simplifies their removal from the filter. In this contribution mobility analyses of water droplets on monofilaments in air are performed. Studies of droplet evaporation on pure PET fibres and on nanorough fibres coated with SiO2 nanoparticles of diameters between 6 nm and 50 nm in a hydrophilic binder system were done. We show that the mobility of water droplets correlates with the droplet conformation which in turn is determined by the droplet-fibre interface. We demonstrate that fibre coatings can be used to tailor the conformation and mobility of water droplets. The smaller the nanoparticle diameters in the coating are, the smaller are the contact angles between water droplets and fibre and the better is the mobility of the droplets on the fibre. Our results allow a fast optimization of the fibre surface properties which are directly influencing the contact angle, the mobility and the coalescence of water droplets and thus filter regeneration.
ABSTRACT
Amantadinesulfate is a well known substance which has proven useful in the treatment and prophylaxis of viral infections, in treating symptoms of Parkinson's disease, cocaine dependence, and apathy in multiple sclerosis. It has also been reported as having mild antidepressive effects not sufficient to warrant its use as an antidepressant. Striking antidepressive effects in some patients have been attributed to its antiviral activity against human Borna disease virus (BDV) infection which is frequently seen in patients with depressive episodes. In this 8 to 12 week open study of oral amantadine in 30 depressed patients with various states of BDV infection we found a significant antidepressive response in 19 of 30. Peripheral BDV antigen indicating acute infection was cleared in both responders and non-responders, but only in responders peripheral infection was significantly reduced.

Emigration is often followed by psychic disorders. The special issue of Germans from the GUS-States immigrating to Germany is presented. The modus of paranoid reaction is discussed along the biography and the criteria of ICD 10. The acute paranoid psychosis was complicated by a neuroleptic malignant syndrome.
