Growth of vapor-deposited amorphous Zr65Al7.5Cu27.5 films under oblique particle incidence investigated by experiment and simulation
No full textAmorphous thin film growth is of high scientific interest due to the possibility of identifying growth processes without the superposition of anisotropies. Oblique particle incidence offers the exciting possibility of breaking this isotropy in the plane of the substrate and of creating nanostructure films dependent on the tilt angle, which enters as an additional parameter. We investigate this structure formation and the nature of the underlying atomic-scale processes with experiments and computer simulations. This is achieved by a detailed film characterization using scanning tunneling microscopy and transmission electron microscopy and a numerical analysis of the data as well as with Monte Carlo and continuum growth models. Measures such as rms roughness or spectral power density are utilized for a quantitative characterization and comparison of experiment and theory. This allows us to identify surface diffusion, shadowing, and steering as the main ingredients for oblique film growth
Atomic dynamics in molecular dynamics simulations of glassy CuTi thin films
No full textWe present results on atomic dynamics in metallic glass thin films below the glass transition temperature using molecular dynamics simulations. Thin CuTi films of different compositions are prepared by quenching the liquid to an amorphous state. The atomic dynamics on the amorphous surface and inside the bulk of the samples are quantitatively compared by calculating diffusion constants and jump length distributions. Here, we focus on the collective or single particle character of the diffusion mechanism in dependence of the atom type. In addition, single atom exemplifications are analyzed for the different kinds of atomic dynamics. We find that Cu surface atoms diffuse with a single atom jump dynamics, whereas inside the bulk collective behavior dominates for both species. (C) 2005 American Institute of Physics

Nursing concepts for patients with dementia
No full textNocon M, Roll S, Schwarzbach C, Vauth C, Greiner W, Willich SN. Nursing concepts for patients with dementia. ZEITSCHRIFT FUR GERONTOLOGIE UND GERIATRIE. 2010;43(3):183-189.Today there are approximately one million people with dementia in Germany. Because most forms of dementia cannot be cured the focus of treatment is to provide adequate care, aiming at the maintenance of cognitive functioning, the ability to perform everyday tasks and quality of life. Important approaches for dementia care are multisensory stimulation, validation, reality orientation and reminiscence therapy. However, the efficacy of these approaches is unclear. A systematic review of the literature was performed. We included randomised controlled trials with at least 30 participants on the efficacy of multi-sensory stimulation, validation, reality orientation and reminiscence therapy for dementia. No restrictions were defined with regard to the endpoints under investigation. A total of 14 studies with 1,513 patients could be included of which 5 studies assessed reminiscence therapy, 4 multi-sensory stimulation, 3 validation and 2 reality orientation. The studies analysed cognitive functioning, behavioural outcomes, psychological symptoms and quality of life. Most studies did not find significant differences between the intervention and the control group. The studies conducted to date provide only little evidence for the efficacy of the approaches for dementia care considered in this review. However, only few methodologically robust studies could be identified for this review which highlights the need for more interventional studies
Kinetic roughening of laser deposited polymer films: Crossover from single particle character to continuous growth
No full textThe crossover in kinetic roughening of thin films from a particle-character-dominated regime to continuous growth behavior has been observed in this work. This has been accomplished by atomic force microscopy investigations of pulsed laser deposited amorphous organic films with thicknesses ranging from several nanometers to more than 4 mum. The early-stage random-deposition-like processes end once a closed layer is formed, which grows without saturation on the characteristic length scales. In addition, the influence of oblique film deposition has been examined and interpreted
Methods for determining cost-benefit ratios for pharmaceuticals in Germany
No full textSchulenburg J-MG v. d., Vauth C, Mittendorf T, Greiner W. Methods for determining cost-benefit ratios for pharmaceuticals in Germany. EUROPEAN JOURNAL OF HEALTH ECONOMICS. 2007;8(S1):5-31.The aim of this methodological paper is to summarize evidence on how to implement cost-benefit assessment according to the new German legislative framework (Competition Enhancement Act). Given the complexity of existing health policy frameworks within industrialised countries in adapting health economics in their respective regulatory scheme, no clear international scientific consensus on which health economic methods should be chosen for assessment can be determined. Nevertheless, a broad consensus on the internal properties of methods itself can be found. Based on these common international standards in methodology, this work provides a minimum catalogue of methods and criteria that meet legal and local German requirements with regard to specific factors of its health care system. Aside from categorising clearly defined standards (e.g., study forms, cost and benefit categories) the suggested catalogue specifies some intensively debated areas in Germany (e.g., the QALY, modelling, the perspective used in the assessment). After the proposition of certain methods the paper leads to a first recommendation of a detailed assessment-process itself specific for the German way in implementing cost-benefit ratios within regulatory decision making in Germany
