  4. 2. Transposable Elements in Neural Progenitor Cells

    Author : Liana Fasching; Molekylär neurogenetik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Transposable Elements; TRIM28; Epigenetic Regulation; Gene Expression; Neural Progenitor Cells;

    Abstract : More than 90% of DNA does not code for proteins and for a long time these sequences were referred to as “junk DNA” due to their unknown purpose. With the advent of new technologies it is now known, that the non-coding part of the genome is of great importance for regulating gene expression and is therefore indispensable. READ MORE

    Abstract : In the modern practice, a sustainable development strategy in a domain of wasteutilization is shifting its focus from a general completeness of recycling to a morespecific attention to efficiently utilize elements in the wastes. This is well-illustrated bythe steelmaking slag industries. READ MORE

  6. 4. The Progressive in 19th-Century English : A Process of Integration

    Author : Erik Smitterberg; Merja Kytö; Marianne Hundt; Uppsala universitet; []

    Abstract : The present work is a corpus-based study of the English progressive during the 19th century. The study is based on Conce, a one-million-word corpus covering the period 1800–1900 and comprising seven genres, both speech-related and non-speech-related. READ MORE

  7. 5. Thermodynamic Modelling of Electrolyte Solutions with Application to the Pulp and Paper Industry

    Author : Anders Jaretun; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Potassium; Chloride; Chemical recovery; Leaching; Crystallization; Kraft pulping; Non-process elements; Solubility; Local composition; Excess properties; Osmotic coefficient; Electrolytes; Activity coefficient; Wood; pulp and paper technology; Pappers- och massateknik;

    Abstract : A thermodynamic model for electrolyte solutions has been derived for binary and multicomponent solutions up to very high molalities. The model was extensively tested on 163 binary aqueous electrolyte systems up to very high molalities, and the results show that the model represents mean ionic activity coefficients and osmotic coefficients very accurately.
