  1. 6. Comparison of properties on Orally Disintegrating Tablets (ODTs) produced by direct compression or fluid bed granulation

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Julia Ahlbom; [2023]
    Keywords : Orally disintegrating tablet; fluid bed granulation; disintegration time; pharmaceutical technology; Technology and Engineering;

    Abstract : Orally disintegrating tablets (ODTs) is a popular drug delivery system as they dissolve in the mouth, usually within seconds which enables easy medication for patients with problem swallowing. In this thesis properties of ODTs were compared when produced with direct compression of the excipients or the excipients were pretreated to form granules in a fluid bed granulator prior to tableting.

  3. 7. Sustainable Production Patterns for Hydropower Units

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Hannington Kayanja; [2023]
    Keywords : Automatic control; Hydropower modelling; PD-controller; Sustainable power production; Water level control.;

    Abstract : Globally, a significant portion of energy comes from hydropower. However, harnessing hydro energy interrupts the natural state of river flows, thus affecting the ecological processes of the surrounding communities. READ MORE

  4. 8. Navigating Large-Scale Plasmid DNA Purification : A Recommendation of Current and Future Downstream Purification Solutions

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Matilda Eriksson; Alva Wells; Maria Frey; Lisa Johansson; Gabriel Pettersson; David Sjöberg; [2023]
    Keywords : Plasmid purification; pDNA; large-scale chromatography;

    Abstract : Previous small-scale methods for plasmid DNA (pDNA) purification fail to meet theindustry’s demand for sufficient quantities. Greater volumes of bacterial lysates are a consequence of larger volumetric fermentations and traditional large-scale down-stream purification processes have some disadvantages and limitations.

  5. 9. Effects of summer peaks on brown trout and Atlantic salmon growth and survival in hydropower-regulated Gullspång River

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Oscar Hallberg; [2023]
    Keywords : hydropeaking; hydropower; fish; salmon; salmo salar; salmo trutta; summer; survival; growth; parr; fry; korttidsreglering; vattenkraft; salmonid; salmo salar; salmo trutta; tillväxt; överlevnad; lax; öring;

    Abstract : Daily demands for electrical power are met through sub-daily release of turbined water in the form of hydropeaking. Hydropeaking’s changes to stream flow are listed as a threat to biodiversity in river ecosystems as it causes rapid habitat alteration such as increased depth and velocity, affecting the species living downstream.

  6. 10. Controls over stream temperature in a northern boreal landscape

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Oskar Damström; [2023]
    Keywords : Aquatic ecosystems; Climate change; Stream warming; Boreal streams;

    Abstract : With widespread increases in air temperature, it is expected that the temperature of aquatic ecosystems will also increase, especially at high latitudes. Warmer streams and rivers could have severe, direct impacts on cold-adapted aquatic fauna but may also indirectly influence species by reducing the amount of suitable habitat. READ MORE
