  1. 1. Developing a protocol for 3D-printable bioink from decellularised porcine tissue

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

    Author : Vendela Sandin; [2024]
    Keywords : Scaffold; Extracellular matrix; ECM; Bioink; Bioprinting; Collagen; Pharmaceutical technology; Technology and Engineering; Biology and Life Sciences;

    Abstract : T-cell administration via a scaffold is a promising tool for treatment of inoperable solid tumours. Traditional scaffold materials lack the complexity of the extracellular matrix (ECM) that cells normally grow in. An alternative is to instead use decellularised ECM (dECM) from biological tissue to create the scaffold. READ MORE

  3. 2. Reactor Chemistry in LWR SMRs : Determination of the rate constant for the reaction between boric acid and hydroxyl radicals

    University essay from KTH/Tillämpad fysikalisk kemi

    Author : Fredrik Petersson; [2023]
    Keywords : LWR; SMR; Water chemistry; Radiolysis; Boric acid; LWR; SMR; vattenkemi; Radiolys; Borsyra; Hydroxylradikal;

    Abstract : Ett problem vid byggandet av nya kärnkraftverk för elproduktion är de stora investeringskostnaderna samt den långa tiden det att få tillstånd för en reaktor och bygga den. Nyligen färdigställdes den tredje reaktorn vid Olkiluoto I Finland, den tog 18 år att färdigställa exklusive tiden att få tillstånd för reaktorn. READ MORE

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Author : Jana Kettunen; Ella Viberg; [2023]
    Keywords : Child; chair; product development; design methods; ergonomic;

    Abstract : The demand for well-adjusted and useable children´s products increase in conjunction with the interest of children’s environment and understanding for how their needs differ from adults. Even if the market has increased the last years an absence still can be perceived of a children’s highchair which is fit for children from six months of age till five years, and at the same time both transportable and aesthetic.

  5. 4. Användning av krävande ballastmaterial vid betongtillverkning - En laborativ utvärdering av absorptionshämmande tillsatsmedel för att möjliggöra användning av glimmerrik bergkross och återvunnen betong som ballast

    University essay from Lunds universitet/Avdelningen för Byggnadsmaterial

    Author : Anna Hagberg; Andreas Andersson; [2023]
    Keywords : Absorption inhibitor; admixtures; aggregate; biotite; calorimetry; compressive strength; concrete; heat development; mica; recycled concrete; workability; Technology and Engineering;

    Abstract : Detta examensarbete utvärderar ett absorptionshämmande tillsatsmedel för att möjliggöra användningen av krävande ballast vid betongtillverkning. Den huvudsakliga anledningen till att ballasten benämns som krävande är att den har ovanligt hög absorptionsförmåga. READ MORE

  6. 5. Rapid expansion of roof mounted PV systems in commercial facilities - How can they be insured?

    University essay from Lunds universitet/Riskhantering (CI); Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

    Author : Erik Lindén; [2023]
    Keywords : PV system fires; PV component failures; PV regulations; future PV regulations; PV risk assessment; PV risk evaluation; PV insurance price; Technology and Engineering;

    Abstract : PV system components that are exposed to unmanageable strain can be overheated, which subsequently results in a fire ignition. Common failure factors are poor component quality, mechanical exposure due to natural phenomena and poor craftmanship. The underlying problem is that PV regulations are lacking in quality or are non-existent. READ MORE
