  1. 1. Structure and dynamics of complex materials in the water-poor regime

    Författare :Sanna Gustavsson; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hydration; cellulose; dissolution; sugar surfactant; hydrated crystals; structure; dynamics; phase diagram; fuel cell; pulsed-field-gradient PFG spin-echo NMR; Polarization Transfer solid state NMR; PXRD; GVS; TGA; amphiphilic;

    Sammanfattning : In the solid state, molecules are normally ordered in a specific structure. With time, and as a result of influence from the surroundings, solid materials can change their molecular and/or crystal structure and, as a consequence, obtain completely different properties. Water is particularly important in this respect. LÄS MER

  3. 2. Neuronal mechanisms of feedback postural control

    Författare :Li-Ju Hsu; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :postural control; equilibrium; body configuration; reticulospinal neurons; stretch receptor neurons; galvanic vestibular stimulation; artificial feedback; locomotion; spinalization; rabbit; lamprey;

    Sammanfattning : Different species maintain a basic body posture due to the activity of the postural control system. An efficient control of the body orientation, as well as the body configuration, is important for standing and during locomotion. LÄS MER

  4. 3. Biological Pretreatment and Dry Digestion Processes for Biogas Production

    Författare :Regina Patinvoh; Thierry Ribeiro; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solid wastes; Dry anaerobic digestion; Textile bioreactor; Plug flow bioreactor; Digestate; Process stability; Pretreatment; Co-digestion; Mesophilic; Resource Recovery; Resursåtervinning;

    Sammanfattning : Biogas technology has been used quite extensively to generate renewable energy from organic wastes while also recycling nutrients in the wastes and reducing harmful emissions. However, the challenges of low biogas yield from recalcitrant and inhibitory solid wastes together with high construction and operation costs of bioreactors have impeded optimal performance through this process.

  5. 4. Pretreatment of cellulosic waste and high rate biogas production

    Författare :Solmaz Aslanzadeh; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biogas; Two-stage anaerobic digestion; N-methylmorpholine N-oxide NMMO pretreatment; Lignocelluloses; Textile waste; Biofuels; Resursåtervinning; Resource Recovery;

    Sammanfattning : The application of anaerobic digestion technology is growing worldwide, mainly because of its environmental benefits. Nevertheless, anaerobic degradation is a rather slow and sensitive process. One of the reasons is the recalcitrance nature of certain fractions of the substrate (e.g. LÄS MER

  7. 5. Biogas Production from Lignocelluloses : Pretreatment, Substrate Characterization, Co-digestion and Economic Evaluation

    Författare :Anna Teghammar; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biogas; lignocellulose; pretreatment; anaerobic digestion; co-digestion; substrate characterization; economic evaluation; Biotechnology;

    Sammanfattning : Biogas production from organic materials can be used as a renewable vehicle fuel, provide heat and generate electricity and can thereby reduce the greenhouse gas emissions. This thesis focuses on the biogas production based on lignocelluloses. There is an abundant availability of lignocelluloses, constituting 50% of the total biomass worldwide. LÄS MER
