  1. 16. The impact of climate change on aquatic systems and phytoplankton communities : A quantitative study of the impacts of altering food-quality on microzooplankton growth rate

    University essay from Institutionen för ekologi, miljö och botanik

    Author : Linnéa Joandi; [2013]
    Keywords : Climate change; phytoplankton communities; microzooplankton; B. Plicatilis; Euplotus sp.; P-limitation; N-limitation; nutrient replete conditions;

    Abstract : A global increase in atmospheric CO2 and temperature is assumed to affect the marine ecosystems in numerous ways, e.g. by altering ocean circulation patterns and changing nutrient regimes. The changes are expected to impact heavily on both phytoplankton communities as well as the rest of the marine food-web. READ MORE

  3. 17. Micro-Structuring of New Materials Combined with Electronic Polymers for Interfaces with Cells

    University essay from Biomolekylär och Organisk Elektronik; Tekniska högskolan

    Author : Alexander Vastesson; [2012]
    Keywords : Off-Stoichiometry Thiol-Ene; Polydimethylsiloxane; Microsystems; Nanosystems; Conducting polymers; HEP G2 cells; Cell viability; Soft lithography; DNA;

    Abstract : Materials based on novel Off-Stoichiometry Thiol-Ene polymers, abbreviated OSTE, show promising properties as materials forlow cost and scalable manufacturing of micro- and nanosystems such as lab-on-chip devices. The OSTE materials have tunablemechanical properties, offer possibility for low temperature bonding to many surfaces via tunable surface chemistry, and can beused in soft lithography. READ MORE

  4. 18. Assessment of humidity management effects on PEM fuel cell performance

    University essay from KTH/Energiteknik

    Author : Ose Micah Osamudiamen Ose Micah; [2011]
    Keywords : PEM Fuel Cell.;

    Abstract : The electrical energy output and the performance of a PEM fuel cell is dependent on the ion transfer in the fuel cell. The ion transport mechanism in the electrolyte cell membrane is dependent on the charge site in the membrane. READ MORE

  5. 19. Approaching determination of H+-ATPase H+/ATP stoichiometry

    University essay from Lunds universitet/Kemiska institutionen

    Author : Stanislaw Wosicki; [2011]
    Keywords : biokemi; Chemistry;

    Abstract : The plant plasma membrane H+-ATPase was activated by the binding of a 14-3-3 protein. This complex can be stabilized by the fungal toxin - fusicoccin. During this activation H+/ATP stoichiometry changed (1). This work presents approaching to find the new stoichiometry. READ MORE

  6. 20. Hydrogen production in Escherichia coli : Genetic engineering of the formate hydrogenlyase complex

    University essay from Institutionen för fysik, kemi och biologi; Tekniska högskolan

    Author : Charlotte Hjersing; [2011]
    Keywords : Escherichia coli; Formate hydrogenlyase; Hydrogenase; Oxygen tolerance;

    Abstract : Biofuels that are renewable and environmentally benign constitute an important area of research, as the supply of fossil fuels decreases and the amount of green house gases in the atmosphere increases. Biohydrogen is not as well explored as other biofuels, but its properties render it a promising complement, as it is clean and can be used directly in fuel cells to generate electricity, the only waste products being water and heat.
