  1. 1. Biocatalysis in Pickering emulsions

    Master-uppsats, Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

    Författare :Christine Vera Isabel Schmidt; [2023]
    Nyckelord :Enzymes; Pickering emulsion; Amine Transaminases; Green Chemistry; Stereoselectivity; Biotechnology; Biology and Life Sciences;

    Sammanfattning : Employing enzymes as catalysts in the production of chiral amines that are both used as building blocks and active pharmaceutical ingredients might be promising due to milder reaction conditions compared to non-biological catalysts, exclusion of heavy metals, high selectivity towards substrates and precision in chirality of the products. Transaminases are attractive for the use in this process. LÄS MER

  3. 2. Promote neuroprotection and axonal outgrowth in the central and peripheral neural system

    Kandidat-uppsats, Uppsala universitet/Institutionen för medicinsk cellbiologi

    Författare :Elin Petersson; [2021]
    Nyckelord :Spinal cord injury; interleukin-1 receptor antagonist; excitotoxicity; qPCR; dorsal root ganglion.;

    Sammanfattning : Acute spinal cord injury is often caused by collisions with motor vehicles, falls or violence. This injury could potentially lead to paraplegia or tetraplegia, causing great economic and personal loss. The patophysiology is biphasic, with primary and secondary mechanisms. LÄS MER

  4. 3. An investigation of the relationships between electrotactile stimulus parameters, primary afferent response, and perceived sensation

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Jessica Sofie Louise Vidmark; [2018]
    Nyckelord :electrotactile stimulation; psychophysical sensation; primary afferent response; sensory feedback; prosthetics; elektrisk hudstimulering; psykofysisk respons; primärafferent respons; sensorisk återkoppling; proteser;

    Sammanfattning : Sensory feedback possesses the possibility of adding a new dimension to many applications, including, but not limited to, prosthetics and surgical robots for improved control, virtual reality for incorporation of another sense, and phantom limb pain reduction for amputees. Electrotactile stimulation provides a compact, light-weight, energy efficient, highly responsive, and non-invasive option for sensory feedback; however, it has been found to commonly elicit unnatural or uncomfortable sensations for the user.

  5. 4. Development and application of a multidomaindynamic model for direct steamgeneration solar power plant

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Anthony Rousset; [2017]
    Nyckelord :Concentrated Solar Power CSP ; Direct Steam Generation DSG ; dynamic modelling; co-simulation; thermal-hydraulic calculation; two-phase flow; Ledinegg instabilities; control-command; regulation; PID controller.; Koncentrerad solenergi CSP ; Direkt ånggenerering DSG ; dynamisk modellering; co-simulering; termisk hydraulisk beräkning; tvåfasflöde; Ledinegg instabiliteter; kontrollkommando; reglering; PID-kontroller..;

    Sammanfattning : Nowadays, one of the solutions considered in order to face the issue of global warming and to move towards a carbon neutral society relies on the use of solar energy as a renewable and bountiful primary source. And, if photovoltaic technologies account for a large part in the solar energy market, recent years have witnessed the growth of non-concentrated and concentrated solar thermal technologies. LÄS MER

  7. 5. CO2 absorption in power plants : Emphasizing on CO2 absorption in biphasic solvent

    Magister-uppsats, Högskolan i Gävle/Avdelningen för bygg- energi- och miljöteknik

    Författare :Athina Kouneli; [2016]
    Nyckelord :;

    Sammanfattning : Carbon dioxide, the famous and vital to life gas, is also an important greenhouse gas. Since the combustion of fuels leads to the production of carbon dioxide it had to be expected that since the industrial revolution the concentration of carbon dioxide in the atmosphere was to be rapidly increased.
