  1. 1. The Prevalence of Radioactivity in a Number of Non-Nuclear Industries

    Författare :Torbjörn Gäfvert; Lund Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Kärnfysik; Nuclear physics; zircon; ceramics industry; thorium; TIG welding; waterworks; calcium chloride; dicalcium phosphate; phosphate industry; non-nuclear industries; TENORM; Natural radioactivity; NORM;

    Sammanfattning : Four different non-nuclear industries have been investigated regarding the presence of radioactive elements, with the focus on natural radioactivity. The aim of the studies was to investigate the flow of radionuclides in the processes and/or to estimate doses to exposed workers. LÄS MER

  3. 2. Biomimetic Formation of Calcium Phosphate Based Nanomaterials

    Författare :Wenxiao He; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; superstructure; lyotropic liquid crystal; self-assembly; Calcium phosphate; bone-like apatite; amphiphilic peptide; nanocomposite; biomimetic mineralization;

    Sammanfattning : The intercellular material in bone is a nanocomposite of aligned “hard” inorganics—calcium phosphate (CaP) platelets embedded in the long-range ordered “soft” organic collagen matrix. This elaborate structural arrangement redeems the weaknesses of the individual components (being soft protein or brittle mineral) and gives bone its excellent mechanical properties for the protection and support of our bodies.

  4. 3. The biological and physical performance of high strength dicalcium phosphate cement in physiologically relevant models

    Författare :Michael Pujari-Palmer; Håkan Engqvist; Marjam Karlsson Ott; Christele Combes; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biomaterial; bioceramic; osteoinduction; calcium phosphate; cement; osteoblast; pyrophosphate; Rebamipide; drug delivery; screw augmentation; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Sammanfattning : The chemical properties of calcium phosphate cements (CPCs) are very similar to the mineral phase of bone. CPCs are, consequently, very effective substrates (scaffolds) for tissue engineering; bone and stem cells attach readily, and can proliferate and differentiate to form new bone tissue. LÄS MER

  5. 4. Multivariate Synergies in Pharmaceutical Roll Compaction : The quality influence of raw materials and process parameters by design of experiments

    Författare :Nabil Souihi; Johan Trygg; Jukka Rantanen; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Roll compaction; dry granulation; mannitol; dicalcium phosphate; design of experiments; orthogonal projections to latent structures; critical quality attributes; tablet manufacturing; quality by design; design space; near-infrared chemical imaging; texture analysis; modeling; scale up; instrumented roll; Johanson model;

    Sammanfattning : Roll compaction is a continuous process commonly used in the pharmaceutical industry for dry granulation of moisture and heat sensitive powder blends. It is intended to increase bulk density and improve flowability. LÄS MER

  7. 5. Nanostructured Ceramics - Synthesis and Understanding

    Författare :Farnaz Ghajeri; Wei Xia; Freddy Kleitz; Uppsala universitet; []
    Nyckelord :Material Science; Nanoporouse Silica; Calcium Phosphate; Synthesis; Characterization; Adsorption; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Sammanfattning : During the last years, nanostructured ceramics have been favored for use in the industry due to their beneficial properties. For example, calcium phosphate ceramics with their biocompatible and bioactive characteristics are beneficial in biomedicine. LÄS MER
