  1. 1. Injectable calcium sulphate and calcium phosphate bone substitutes

    University dissertation from Department of Orthopaedics, Lund University

    Author : Malin K Nilsson; Lund University.; Lunds universitet.; [2003]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatologi; ortopedi; Kirurgi; Surgery; orthopaedics; traumatology; resorbable; hydroxyapatite; bone substitute; calcium phosphate; injectable; calcium sulphate;

    Abstract : Two formulations of biphasic injectable bone substitutes have been developed for the treatment of bone defects and stabilisation of fragility fractures. The first formulation consists of a calcium sulphate matrix with embedded hydroxyapatite (HA) particles to provide osteoconductivity. READ MORE

  2. 2. Biomaterials as carriers for bone active molecules-An approach to create off-the-shelf bone substitutes

    University dissertation from Lund University: Faculty of Medicine

    Author : Deepak Raina; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; [2018]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; biomaterials; Bone tissue engineering; Bone morphogenic protein-2; Zoledronic acid ZA ; calcium sulphate; Hydroxyapatite; Gelatin;

    Abstract : Bone tissue is commonly transplanted during orthopedic surgeries, primarily for the management of bone defects caused by trauma or various orthopedic conditions including, but not limited to, infections and tumours. Bone grafts are a surgeon’s choice, but their associated drawbacks are paving the way for biomaterial based bone graft substitutes. READ MORE

  3. 3. Influence of solid solutions on the properties of some apatite-type calcium salts relevant to the production of phosphate and silicate cements

    University dissertation from Simon Jegou Saint-Jean (or Pr. Staffan Hansen), Materials Chemistry, Lund University

    Author : Simon Jegou Saint-Jean; Lund University.; Lunds universitet.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Materiallära; materialteknik; Chemical technology and engineering; Kemiteknik och kemisk teknologi; Material technology; isothermal calorimetry.; Rietveld method; X-ray diffraction; silicon; strontium; Portland cement; calcium phosphate cement; chlorellestadite; Solid solutions; apatite;

    Abstract : The effects of non-stoichiometry and isomorphic substitutions on the properties of some apatite-type compounds were investigated. These investigations were performed both in the fields of Portland cement chemistry and apatitic calcium phosphate-based biocements. READ MORE

  4. 4. Properties of Interfacial Proteinaceous Films with Emphasis on Oral Systems

    University dissertation from Food Technology, Lund University

    Author : Cecilia Hahn Berg; Lund University.; Lunds universitet.; [2003]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; Livsmedelsteknik; trypsin; SDS elutability; statherin; salivary proteins; salivary pellicle; proline-rich proteins; plaque control; mucins; microbial adhesion; lubrication; krillase; intraoral friction; hydroxyapatite; gelatin; exchange; enzymes; ellipsometry; dental plaque; degradation; colloidal probe; calcium-induced precipitation; adsorption; atomic force microscopy; total internal reflectance fluorescence spectroscopy;

    Abstract : The present thesis addresses three issues related to proteinaceous films at solid/liquid interfaces: adsorption, lubrication and enzymatic interactions. Most of the work has been devoted to oral systems. In addition, gelatin has been investigated as a model protein. READ MORE

  5. 5. Flotation chemistry of complex sulphide ores recycling of process water and flotation selectivity

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Fatai Kolawole Ikumapayi; Luleå tekniska universitet.; [2010]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

    Abstract : Recycling of flotation effluents through the ore processing plant is one of the ways of reducing both plant-operating costs and industrial impact onto the local ecosystem. Such waters named acid mine drainage (AMD), if discharged from sulphide flotation are gypsum (CaSO4.H2O) saturated and have a high salinity (on the order of 1000 ppm). READ MORE
