  1. 1. Design of passively loaded specimen for constant KI during crack growth

    University essay from KTH/Hållfasthetslära

    Author : Liisa Tofferi; [2021]
    Keywords : constant KI; passively loaded specimen; konstant KI; passivt belastad provstav;

    Abstract : Passive loading of a specimen is a relatively cheap method to use in fracture mechanical testing compared to an actively loaded specimen. For stress corrosion cracking testing it is easier to use a passively loaded specimen since the specimen easily can be placed in a specific corrosive environment. READ MORE

  3. 2. Kinetic studies of carrier conjugated protease inhibitors

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning; Uppsala universitet/Institutionen för kemi - BMC

    Author : Enrique Argenis López Olvera; [2019]
    Keywords : Proteases inhibitors; bioconjugates; enzyme kinetics; inhibition;

    Abstract : Conjugates of soybean trypsin inhibitor (SBTI) and potato serine protease inhibitor (PSPI) immobilized on metal oxide particles of ~100nm diameter were prepared. Inhibition of trypsin hydrolysis of BAPA by these conjugates was measured and enzyme kinetics constants kcat, KM, kcat/KM and ki were determined. READ MORE

  4. 3. Adsorption of Polyvinyl Alcohol on Nano-Cellulose Fibers

    University essay from Fakulteten för teknik- och naturvetenskap

    Author : Arif Hussain; [2010]
    Keywords : Poly vinyl alcohol ; nano-cellulose fibers; adsorption isotherms;

    Abstract : Nano-cellulose fibers/suspension has very high viscosity, its viscosity has to be lower before it can be applied in the paper coating recipe. For this purpose the adsorption behaviour of polyvinyl alcohol on nano-cellulose fibers were investigated using method developed by Zwick in 1960, based on the formation of PVA-iodide blue complex in the presence of boric acid.

  5. 4. Dosimetric Characteristics of CVD Single Crystal Diamond Detectors in Radiotherapy Beams

    University essay from Medicinsk strålningsfysik (tills m KI)

    Author : Anna Ärlebrand; [2008]
    Keywords : Diamond detector; CVD; Priming dose;

    Abstract : Dosimetric characteristics of a CVD single crystal diamond detector have been evaluated. Detector stability, linearity, optimal bias, temperature dependence, directional dependence, priming and pre-irradiation behaviour, depth dose curves and dose profiles were investigated. The optimal bias was determined to be 50 V. READ MORE
