- An extensive new caring program--including the introduction of Individual Care Plans and changes in ward organization, caring techniques, and caring philosophy--was introduced at two psychogeriatric wards with severely demented patients. The hypotheses were that the patients (n = 31) would improve in psychosocial capacity and orientation and the staff work load would decline in contrast to two other wards with a similar clientele (n = 31). After ten months the milieu was more "homelike," routines were more flexible, and the staff communicated more with the patients. However, the hypotheses were not proven. All patients in both groups deteriorated in ADL capacity, orientation, and behavior. The patients in the program wards became significantly more restless and disoriented and ate less than the patients in the contrast wards. The conclusion is that, despite optimal care, a humanistic approach, and support from staff, the progression of dementia symptoms is inevitable.

Journal article (peer-reviewed)abstract
- Electrospinning is a process that generates nanofibres. Temperature and humidity affect this process. In this article the influence of humidity and temperature on the formation and the properties of nanofibres are studied using cellulose acetate (CA) and poly(vinylpyrrolidone) (PVP) as target materials. The experiments indicate that two major parameters are dependent of temperature and have their influence on the average fibre diameter. A first parameter is the solvent evaporation rate that increases with increasing temperature. The second parameter is the viscosity of the polymer solution that decreases with increasing temperature. The trend in variation of the average nanofibre diameter as a function of humidity is different for CA and PVP, which can be explained by variations in chemical and molecular interaction and its influence on the solvent evaporation rate. As the humidity increases, the average fibre diameter of the CA nanofibres increases, whilst for PVP the average diameter decreases. The average diameter of nanofibres made by electrospinning change significantly through variation of temperature and humidity. © 2008 Springer Science+Business Media, LLC.
