  1. 16. Solar Assisted Pervaporation (SAP) : A process using membrane pouches and solar energy for the dehydration and preservation of fruit juices in rural and remote areas

    Författare :Randi Phinney; Avdelningen för livsmedel och läkemedel; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; membrane; pervaporation; fruit preservation; solar drying; heat and mass transfer; coupling effects;

    Sammanfattning : Drying has been used for thousands of years to preserve foods. One of the first methods used was open air sun drying which exposes foods directly to solar radiation and ambient air. This method is still used today around the world but it remains underdeveloped on the small-scale for two main reasons. LÄS MER

  3. 17. Fermentative hydrogen and methane productions using membrane bioreactors

    Författare :Julius Akinbomi; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Encapsulation; Inhibition; hydrodynamics; hydrogen; methane; fruit flavour; Membrane bioreactor; Resursåtervinning; Resource Recovery;

    Sammanfattning : The role of energy as a stimulant for economic growth and environmental sustainabilityof any nation has made the focus on green fuels, including fermentative hydrogen (bioH2) andmethane (bioCH4), to be a priority for the World’s policy makers. Nigeria, as the most populousAfrican country, with worsening energy crisis, can benefit from the introduction of the bioH2 andbioCH4 technologies into the country’s energy mix, since such technologies have the potential ofgenerating energy from organic wastes such as fruit waste.

  4. 18. Waste Heat Driven Membrane Distillation for Industrial Wastewater Treatment

    Författare :Imtisal-e- Noor; Andrew R. Martin; Olli Dahl; Mikel Duke; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Membrane Distillation; Experimental investigations; Techno-economic; Wastewater; Flue gas condensate; Waste heat; District heating; Nano-electronics; Cogeneration; Sustainable development; Energy Technology; Energiteknik; Chemical Engineering; Kemiteknik;

    Sammanfattning : The European Union has placed a high priority on reaching the goals described in the 2030 Agenda for Sustainable Development. This aim has provided added momentum to member-state environmental regulatory authorities to further tighten the discharge limits of industrial wastewater. LÄS MER

  5. 19. Cellular electrophysiological modulation in chronic atrial fibrillation - Studies with magnesium and GIK solution

    Författare :Max Ingemansson; Lunds universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Action potential duration; Atrial cycle length; Atrial remodelling; Autonomic nervous system; AV-nodal; Conduction velocity; GIK; Magnesium; Resting membrane potential.; Refractoriness; Atrial fibrillation; Cardiovascular system; Kardiovaskulära systemet;

    Sammanfattning : Although chronic atrial fibrillation (CAF) is the most common sustained cardiac arrhythmia in man, the mechanisms involved in its progressive course are still not fully understood. Recent studies have verified an electrical remodelling of the atrial myocardium that may be responsible for the electrophysiological disturbances known to exist in the fibrillating atria. LÄS MER

  7. 20. Insight into the mitochondrial apoptotic pathway : The interplay of the pro-apoptotic Bax protein with oxidized phospholipids and its counterplayer, the pro-survival Bcl-2 protein

    Författare :Marcus Wallgren; Gerhard Gröbner; Marco Colombini; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; apoptosis; Bax; Bcl-2; CD; cell-free protein synthesis; DSC; membrane; mitochondria; oxidized phospholipids; reconstitution; solid state NMR; biologisk kemi; biological chemistry;

    Sammanfattning : Apoptosis plays a crucial role in multicellular organisms by preserving tissue homeostasis and removing harmful cells. The anti-apoptotic B-cell CLL/lymphoma 2 (Bcl-2) and the pro-apoptotic Bcl-2-associated X protein (Bax) act as major regulators of the mitochondrial apoptotic pathway. LÄS MER
