   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wood-based nanomaterials; process-structure-property relationships; nanocellulose; lignocellulose nanofibers; rheology; small-angle X-ray scattering; lignin; tannic acid; unidirectional ice-templating; foams; aerogels; sustainability; träbaserade nanomaterial; process-struktur-egenskapsrelationer; nanocellulosa; lignocellulosananofibrer; reologi; småvinkelröntgenstrålning; lignin; garvsyra; riktad isstrukturering; skum; aerogeler; hållbarhet; materialkemi; Materials Chemistry;

   Abstract : This thesis presents novel methods and approaches for designing, preparing/fabricating, and characterizing wood-based nanomaterials. It investigates how modifications in structure, process variables, and composition can enhance functional properties. READ MORE

4. 2. Design, processing and properties of lightweight foams from cellulose nanofibers

   Author : Korneliya Gordeyeva; Lennart Bergström; Nathalie Lavoine; Monica Österberg; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; cellulose nanofibers; lightweight foams; hybrid; Materials Chemistry; materialkemi;

   Abstract : Foams are applied in many areas including thermal insulation of buildings, flotation devices, packaging, filters for water purification, CO2 sorbents and for biomedical devices. Today, the market is dominated by foams produced from synthetic, non-renewable polymers, which raises serious concerns for the sustainable and ecological development of our society. READ MORE

5. 3. In Vitro Availability of Iron in High-Tannin Sorghum. Effect of Enzymatic Oxidation of Phenolic Compounds

   Author : Erika Matuschek; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bioavailability; catechol groups; polyphenols; polyphenol oxidase; iron; in vitro availability; tyrosinase; fruit extracts; sorghum; oxidation; tannins; galloyl groups;

   Abstract : Iron deficiency anemia is the most common nutritional disorder in the world. In low income countries, it is to a large extent caused by low bioavailability of iron in the vegetable diet. Vegetable diets contain large amounts of compounds that inhibit iron absorption, e.g. READ MORE

6. 4. Food choice in fallow deer – experimental studies of selectivity

   Author : Ulrika Alm Bergvall; Olof Leimar; Frederick D. Provenza; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; behavioural syndrome; neighbour contrast defence; neighbour contrast susceptibility; simultaneous negative contrast; plant secondary compounds; tannins; Ethology and behavioural ecology; Etologi och beteendeekologi; etologi; Ethology;

   Abstract : In this thesis, I experimentally investigate feeding selectivity in fallow deer (Dama dama), with respect to plant secondary compounds, especially tannins, which can decrease the quality of foods. I found that fallow deer avoided foods with higher amounts of tannic acid and Quebracho tannin, even though the deer ate some high-tannin food. READ MORE

7. 5. Exposure to indoor allergens and relation to sensitization and asthma in children

   Author : Abdul Kashem Mohamma Munir; Ulrich Wahn; Linköpings universitet; []
   Keywords : MEDICINE; MEDICIN;

   Abstract : The indoor environment plays a major role for sensitization and elicitation of allergic disease. In this thesis major allergens from house dust mite, cats and dogs were quantitated in dust samples from various indoor locations, i.e. homes of children, Day-care centers and schools. READ MORE
