  2. 21. 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

  4. 22. Anaemia and iron deficiency in children and women in Tanzania. Effects of dietary iron intake, low iron bioavailability and supplementation with multiple micronutrient beverage

    Author : Simon Tatala; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; serum ferritin; haemoglobin; multiple micronutrient beverage; dietary iron intake; anaemia; serum retinol; iron deficiency; children and Tanzania; pregnant women; iron bioavailability;

    Abstract : Anaemia was investigated in a rural Tanzanian community to determine its magnitude and causative factors in different population groups. Nutritional anaemia resulting mainly from a diet with a low bioavailability of iron affected more than half of the total number of women and children. READ MORE

  5. 23. Surface Engineering of BiVO4-based Photoelectrochemical Cells for Water Splitting

    Author : Qijun Meng; Licheng Sun; Jae Sung Lee; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; photoelectrochemical water splitting; photoanodes; bismuth vanadate; surface engineering; Kemi; Chemistry;

    Abstract : Photoelectrochemical (PEC) water splitting is a promising technology for converting solar energy into green hydrogen. The development of highly efficient, robust and cost-effective photoanodes has been established to be of essential importance for PEC water oxidation. READ MORE

  6. 24. Factors Influencing Iron Dialyzability and Uptake in In Vitro Models

    Author : Susan Salovaara; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ferric iron; iron dialyzability; Caco-2 cells; pea protein; organic acids; gastrointestinal model; transit time; iron absorption; ferrous iron;

    Abstract : The availability or iron from a meal is influenced by numerous factors. This thesis deals with three of them: organic acids, plant proteins (pea and soy), and transit time through the stomach and small intestine. READ MORE

  7. 25. Ash transformation in thermochemical conversion of different biomass resources with special focus on phosphorus

    Author : Ali Hedayati; Marcus Öhman; Christoffer Boman; Kentaro Umeki; Anita Pettersson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; agricultural biomass; forest residues; sewage sludge; ash transformation; release; potassium; phosphorus; combustion; gasification; bio charcoal; phosphorus recovery; Energy Engineering; Energiteknik;

    Abstract : A great potential exists for increasing the use of bioenergy in thermochemical processes by utilizing agricultural biomass, forest residues, and sewage sludge that have high availability. Many of these biomass assortments have high ash contents with relatively high concentrations of ash-forming elements such as potassium (K), calcium (Ca), silicon (Si), and phosphorus (P). READ MORE
