In Scanning Transmission X-ray Microscopy (STXM) a micro focused soft x-ray beam is generated by a zone plate, illuminates the sample and the transmitted x-rays are detected. Transmission images are obtained by a raster scan of the sample. Spectra are obtained in point, line or image mode by acquiring signal at multiple photon energies. The 5.3.2STXM is an interferometrically controlled device mounted on a dedicated bending magnet beamline. The user controls both the beamline and the microscope from a single computer.

YouTube, Podcasting, Blogs, Wikis and RSS are buzz words currently associated with the term Web 2.0 and represent a shifting pedagogical paradigm for the use of a new set of tools within education. The implication here is a possible shift from the basic archetypical vehicles used for (e)learning today (lecture notes, printed material, PowerPoint, websites, animation) towards a ubiquitous user-centric, user-content generated and user- guided experience. It is not sufficient to use online learning and teaching technologies simply for the delivery of content to students. A new “Learning Ecology” is present where these Web 2.0 technologies can be explored for collaborative and (co)creative purposes as well as for the critical assessment, evaluation and personalization of information.

An important concern is that posting personal information on social websites such as Facebook, MySpace and Bebo is putting children at risk of abuse. Our survey of children at Key Stages 3 and 4 shows that a substantial minority (42%) of children regularly interact socially online with people they have not met face to face. This does not, of itself, indicate that children are naive or engaging in behaviour that puts them at significant risk. Rather, it shows that online interaction forms a different, though overlapping, social space to that of face-to-face friendships, involving friends of friends and people encountered in the online world, for example, through multiplayer games.

We’ll briefly demonstrate a very simple example of Photoshop’s ability to create interesting images entirely from scratch, rather than merely editing existing image material. We’ll be creating a colorized lightning bolt. First, create a new image. Make it 800 x 600 pixels in size, at 72 pixels/inch (recall this is the resolution of a monitor), and make the background contents transparent. Make sure the color mode is RGB.
