Charakterisierung von Plasma‐ Polymerfilmen mittels Flugzeit‐ Sekundärionen‐Massenspektrometrie (ToF‐SIMS). Characterisation Plasma‐Polymerfilms by Time‐of‐Flight Secondary Ion Mass Spectrometry (ToF‐SIMS)

Time‐of‐Flight Secondary Ion Mass Spectrometry (ToF‐SIMS) is a surface sensitive analytical method which is utilised in many scientific and industrial branches. The area of application is the identification and localisation of all elements as well as organic and inorganic chemical compounds on arbitrary solid surfaces. The information on the surface is obtained from mass spectra. Due to the high mass resolution (m/Δm > 5.000) different chemical species of the same nominal mass can be clearly separated from each other. Furthermore, the lateral distribution of elemental and molecular species on the surface can be displayed with a lateral resolution < 1 μm. By multivariate modeling the complete information from the mass spectra can be correlated with physical surface properties such as wetting behaviour, elemental concentrations, tribological parameters etc. The outcome of this are decisive information about the functionality of the analysed surface structure. For this reason Time‐of‐Flight Secondary Ion Mass Spectrometry becomes an essential analysis tool in the development of functional surfaces which are the basis of novel and innovative products.     

Characterisation of amorphous carbon coatings for magnetic storage devices via AFM‐Nanoscratching devices. AFM‐Nanoscratching an amorphen Kohlenstoffschichten für die Speichertechnologie

The mechanical properties of ultra‐thin amorphous carbon films used as protective coatings for magnetic storage devices were investigated by means of atomic force microscopy (AFM). Diamond‐tipped cantilevers were used in order to generate scratches with residual scratch depths of only a few Angstroms and even below. The presented method simulates mechanical strains at the head‐disk interface. A driftcompensating image subtracting technique allows the visualisation of these ultra‐shallow scratches and enables the mechanical characterisation of only few Nanometer films widely independent from the hardness of the substrate. The scratch resistance as it is defined here correlates well with the mass density and the sp³ content of the investigated films.     

The not-so-simple art of imitation: Pastiche, literary style, and Raymond Chandler

This analysis extends the tools of statistical analysis to the challenging task of distinguishing between genuine works by an author, the preeminent American writer of mysteries, Raymond Chandler, and deliberate attempts by others to mimic the author's style. Rendering the task all the more challenging, the analysis focuses exclusively on the main elements of Chandler's style rather than on his minor but telling stylistic idiosyncrasies. Statistical analysis establishes that indicators of these stylistic elements can successfully detect the pastiches.Lee Sigelman is Professor and Chair of Political Science at The George Washington University. His research interests range widely throughout the social sciences, including research methods, mass communication, political behaviour, and popular culture. With Ernest Yanarella, he co-edited Political Mythology and Popular Fiction, and has published several articles on political themes in popular literature.William Jacoby is an associate professor in the Department of Government and International Studies at the University of South Carolina. His work has focused substantively on mass political attitudes and behavior. He has a strong interest in statistical methods, and has written extensively on dimensional analysis.     

Felt versus enacted stigma: a concept revisited. Evidence from a study of people with epilepsy in remission

Epilepsy is, in the majority of cases, a short-lived and self-limiting clinical condition. However, individuals labelled as epileptic frequently continue to feel stigmatised, even after their seizures remit. This paper describes the nature and extent of stigma in a group of individuals with epilepsy in remission. The distinction between 'felt' and 'enacted' stigma is examined, and found to be supported by the data.     

Cardiovascular profile of mixidine fumarate, a compound which attenuates myocardial chronotropic responses

The effect of mixidine fumarate on myocardial chronotropic responses to various stimulants was examined. Mixidine decreased elevated heart rate in the anesthetized dog to basal levels. It produced a dose-related decrease in heart rate elevated reflexly by aminophylline, by beta adrenergic stimulation induced by isoproterenol, by sympathetic nerve stimulation and by intravenous infusion of glucagon. Mixidine attenuated the increase in contractile force produced by sympathetic nerve stimulation but not that induced by isoproterenol. The compound antagonized the increase in rate of isolated guinea-pig atria induced by both isoproterenol and histamine. In the conscious dog, mixidine caused no decrease in resting heart rate, mean arterial pressure and cardiac output. It reduced atropine-induced sinus tachycardia as well as that induced by treadmill exercise. Experiments in the dog heart-lung preparation indicated that attenuation of an epinephrine-induced sinus tachycardia led to a decrease in myocardial oxygen consumption and an increase in myocardial efficiency. These studies suggest that mixidine fumarate induces an antichronotropic activity by a direct effect on the sinoatrial node and by attenuating sympathetic nervous system input to the heart.
