One single storage and retrieval system allows efficiency and extensibility not possible under KDE 3, where each PIM component had its own system. Note that use of Akonadi does not change data storage formats (vcard, iCalendar, mbox, maildir etc.) - it just provides a new way of accessing and updating the data.</p><p> The main reasons for design and development of Akonadi are of technical nature, e.g. having a unique way to ac- cess PIM-data (contacts, calendars, emails..) from different applications (e.g. KMail, KWord etc.), thus eliminating the need to write similar code here and there.</p><p> Another goal is to de-couple GUI applications like KMail from the direct access to external resources like mail-servers - which was a major reason for bug-reports/wishes with regard to perfor- mance/responsiveness in the past.</p><p> More info:</p><p> <a href=https://community.kde.org/KDE_PIM/Akonadi target=_top>Akonadi for KDE’s PIM</a></p><p> <a href=https://en.wikipedia.org/wiki/Akonadi target=_top>Wikipedia: Akonadi</a></p><p> <a href=https://techbase.kde.org/KDE_PIM/Akonadi target=_top>Techbase - Akonadi</a> See Also "GUI".

Calligra Chapter 1 Introduction 1.1 Calligra components IMPORTANT Please check http://docs.kde.org for updated versions of this document. Calligra is a graphic art and office suite by KDE. Calligra consists of the following components: • Calligra Words (a frames-based wordprocessor) • Calligra Sheets (a spreadsheet application) • Calligra Stage (screen and slide presentations) • Calligra Flow (a flowchart application) • Calligra Karbon (a vector drawing application) • Calligra Plan (a project management application) Because these components use Flake technology, Calligra components are designed to work very well with each other. Many Calligra component can be embedded in another Calligra document. For instance, you can insert a spreadsheet which you created in Calligra Sheets directly into a Calligra Words document. In this way, complex, compound documents can be created using Calligra. A plugin mechanism makes it easy to extend the functionality of Calligra. You will find many plugins in some of the components and can learn how to write plugins yourself.

  • The Flake Graphite Prospect of Piippumäki—An Example of a High-Quality Graphite Occurrence in a Retrograde Metamorphic Terrain in Finland
    Mineralium Deposita https://doi.org/10.1007/s00126-020-00971-z ARTICLE The flake graphite prospect of Piippumäki—an example of a high-quality graphite occurrence in a retrograde metamorphic terrain in Finland J Palosaari1 & R-M Latonen2 & J-H Smått3 & SRaunio4 & OEklund1 Received: 21 January 2019 /Accepted: 3 March 2020 # The Author(s) 2020 Abstract The flake graphite occurrence in Piippumäki, Eastern Finland, as indicated by an airborne electromagnetic anomaly, was located during fieldwork by electromagnetic measurements with Slingram. The anomaly is approximately 0.1 × 1 km in size. The flake graphite is hosted by quartz-feldspar gneiss and amphibolite that have been subjected to retrograde metamorphism. This is observed in thin sections as granulite facies (garnet + cordierite + sillimanite + melt) regressing to greenschist facies (epidote, chlorite, albite, and white mica). The graphite (up to 1 mm large flakes) is found in graphite-bearing layers in the gneiss, and to a minor extent disseminated in the amphibolite. The average total sulfur (TS) is 0.33%, total carbon (TC) is 6.49%, and the average content of graphitic carbon (Cg) is 6.41% for the analyzed graphite-bearing rocks. SEM, XRD, and Raman spectroscopy were used for analyzing the flake graphite, indicating that the graphite is almost defect-free, of high quality, and has not been affected by the retrograde metamorphism. The peak metamorphic temperature of 737 °C was determined by a Raman thermometer, and no temperatures of greenschist facies were observed. A pseudosection was constructed from whole-rock chemical composition and indicated equilibration at ca 5 kbar and 740 °C, which corresponds to the observed mineral assemblages.
