  1. 1. Process analytical methods for monitoring of the film coating on pharmaceutical pellets and tablets using NIR spectrometry and image analysis

    Author : Martin Andersson; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; PLS; PCA; PAC; NIR; chemometrics; moving samples; information depth; release rate; image analysis; near infrared; process analytical chemistry; thickness; coating; film; tablets; Pellets; granules; Analytical chemistry; Analytisk kemi;

    Abstract : Pharmaceutical tablets and pellets are often covered with a coating. There is a need for methods that enable monitoring of the growth of such films during processing. Such analyses can be performed using process analytical chemical methods based on near infrared (NIR) diffuse reflectance spectrometry. It provides with analyses that take only ca. READ MORE

  2. 2. Terahertz sensing for non-destructive characterisation of pharmaceutical tablets

    Author : Anis Moradikouchi; Chalmers University of Technology; []
    Keywords : sensing.; non-destructive; pharmaceutical tablets; Terahertz technology; frequency domain; dielectric characterisation; porosity measurements;

    Abstract : The pharmaceutical industry is shifting from conventional batch manufacturing to continuous manufacturing. To realise continuous manufacturing, it is crucial to assess the product quality of tablets at different stages of the production line. READ MORE

  3. 3. Digital play in preschools : understandings from educational use and professional learning

    Author : Leif Marklund; Elza Dunkels; Kenneth Ekström; Åsa Bartholdsson; Umeå universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; digital play; preschool; digitalisation; tablets; professional learning; professional development; early years; digital competence; literacy; workplace learning; preschool teachers; early childhood education; technology integration; pedagogiskt arbete; educational work;

    Abstract : The purpose of this thesis is to improve knowledge on preschool teachers’ educational use of digital play and their professional learning about it. The thesis is focused on three questions; How can preschool teacher educational use of digital play be understood? How can the professional learning context of preschool teachers using digital play for educational purposes be understood? And, How can preschool teacher knowledge needs concerning educational use of digital play be understood?  The participants were preschool teachers who had started to introduce tablets and digital play in educational practice.
