Fluorescent Screen

In this form of electron microscopy, photoelectrons emitted from a metal by ultraviolet radiation are accelerated and imaged onto a fluorescent screen by conventional electron optics. image contrast is determined by spatial variations in the intensity of the photoemission. The dominant source of contrast is due to changes in the photoelectric work function, between surfaces of different crystalline orientation, or different chemical composition. Topographical variations produce a relatively weak contrast due to shadowing and edge effects.Since the photoelectrons originate from the surface layers (e.g. ∼5-10 nm for metals), photoelectron microscopy is surface sensitive. Thus to see the microstructure of a metal the thin layer (∼3 nm) of surface oxide must be removed, either by ion bombardment or by thermal decomposition in the vacuum of the microscope.

Abstract Individuals with significant communication challenges need to communicate across many different venues. The author, from the perspective of an individual who uses AAC, discusses the strengths and weaknesses of both traditional AAC technologies and new mobile AAC technologies. He describes how access to AAC has allowed him to fulfill his dreams as a presenter and writer. He successfully manages a blog in San Francisco, writes grants, and has published his first book of poetry. Not one AAC device fits all of his communication needs; however, access to mobile technology tools has increased his flexibility across environments and given him another successful tool for communication.

Jedes Jahr erleiden rund 270 000 Deutsche einen Schlaganfall. Obwohl die Ursachen eines Schlaganfalls sehr unterschiedlich sind, bilden die aktuellen Richtlinien individuelle Eigenschaften des Patienten nicht ausreichend ab. Forscher der Berliner Charité suchen Abhilfe und entwickeln mithilfe von künstlicher Intelligenz personalisierte Vorhersageanalysen für die Schlaganfalltherapie und Prävention.

The Brexit referendum in 2016 was a major turning-point in British and Scottish politics, reflected in a majority for Leave in England, but for Remain in Scotland. This article uses the British and Scottish Social Surveys for 2016 to explain Scottish-English differences, and finds that there were broad similarities in terms of social and demographic characteristics, and in terms of social values (‘authoritarians’ voting for Leave). Being ‘English’, however, was much more significant than being ‘Scottish’ in accounting for Brexit vote. The association between Brexit vote and constitutional preferences, notably voting intention in a future Scottish Independence Referendum, is far less clear-cut. Brexit promises to be a political game-changer, but in ways which are complex and unpredictable.
