  1. 1. Development of bixin formulations. Extraction, microencapsulation, dispersibility and photostability

    Author : Cecilia Curi; Institutionen för livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bixin; annatto; natural colorants; light stability in solid multiphase systems; shelf life extension; auqeous physical stability; encapsualtion efficiancy; spray drying; natural colored candies;

    Abstract : The aril that covers the seeds of the plant species Bixa orellana is composed of the natural colorants bixin and norbixin, phenolic components and native carbohydrates composed of hemicellulose, starch, and a small fraction of proteins. Bixin is a hydrophobic carotenoid that is water insoluble and is mostly used for coloring oil-based formulations. READ MORE

  2. 2. Micro-pitting and wear characterization for crankshaft roller bearing application

    Author : Aleks Vrček; Pär Marklund; Exa Vuorinen; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Elements; Maskinelement;

    Abstract : Efficiency of internal combustion engines (ICEs) is far from optimal. Due to the continuously increasing demands on CO2 regulations, automobile industries are forced to improve such efficiency. A crankshaft roller bearing (CSRB) can lead to significant improvements in engine efficiency. READ MORE

  3. 3. Scots pine (Pinus sylvestris L.) sapwood modification by vinyl acetate-epoxidized plant oil copolymer : precursor syntheses, characterization, modified wood properties and durability

    Author : Shengzhen Cai; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; LANTBRUKSVETENSKAPER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; AGRICULTURAL SCIENCES;

    Abstract : A new bio-based formulation consisting of plant oil and vinyl acetate was developed for wood modification aiming at improving some of the material’s properties. In–situ epoxidation of linseed oil (LO) and soybean oil (SO) was carried out at different times with purpose of preparing epoxidized oils with various epoxy content. READ MORE

  4. 4. Methods for Preclinical Evaluation of Cytotoxic Drugs : With Special Reference to the Cyanoguanidine CHS 828 and Hollow Fiber Method

    Author : Saadia Bashir Hassan; Elin Lindhagen; Rolf Larsson; Mats O Karlsson; Mustapha Hassan; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacology; CHS 828; in vitro; in vivo; hollow fiber; models; NF-kB; Farmakologi; Pharmacological research; Farmakologisk forskning;

    Abstract : The novel cyanoguanidine CHS 828 has shown promising antitumor activity in many in vitro and in vivo studies. The long-term 14 days in vitro hollow fiber cultures, where tumor cells from different tumor cell lines were cultured inside semipermeable fibers, were more resistant to CHS 828 and other cytotoxic drugs than the shorter-term 3 days cultures.

  5. 5. Non-linear model applied on composites exhibiting inelastic behavior: development and validation

    Author : Liva Pupure; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymeric Composite Materials; Polymera konstruktionsmaterial;

    Abstract : The polymeric composite materials are in high demand by industries where light and strong materials are required. Although manmade fiber (e.g. glass, carbon, aramid fibers) are most often used to reinforce polymers, natural fibers due to their environmental friendliness and sustainability have been also considered.
