  2. 1. Additives Increasing the Bone-Forming Potential around Calcium Phosphate Cements : Statin, Strontium and Silicon

    Author : Maryam Montazerolghaem; Marjam Karlsson Ott; Håkan Engqvist; Pedro Granja; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Calcium Phosphate Cements; Osteoblast; Osteoclast; Monetite; Zebrafish; Simvastatin; Strontium; Silicon; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Abstract : More than one million people worldwide receive some kind of bone graft each year. Grafts are often needed following bone tumour removal or traumatic fractures to fill voids in the bone and to aid in the healing process. READ MORE

  5. 3. Bone Healing after implantation of bone substitute materials. Experimental studies in estrogen deficiency

    Author : Sven Öberg; Jan Rosenquist; Ulf Lekholm; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Bone grafts; hydroxyapatite; estrogen deficiency; demineralised bone; bone formation; AAA bone; bone defect; titanium implants; resonance frequency analysis.; Kirurgi; Surgery; Kirurgi; kirurgi; Surgery;

    Abstract : Bone formation and bone healing were studied in the mandible, tibia and skull bones in adult, healthy and estrogen deficient rabbits implanted with different bone substitutes.In the first study an evaluation of the differences in bone regeneration in and around solid (Alveograf *) and porous hydroxyapatite (Interpore 200*) was undertaken.

  6. 4. Recovery and reuse of TiO2 and other pigments from paint waste

    Author : Mikael Karlsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Titanium dioxide; Paint Waste; Recovery; Pyrolysis;

    Abstract : Titanium dioxide (TiO2) has numerous applications in our society, most notably as a white pigment in products such as paint, paper and plastic. Since 2010 there has been a sharp increase in the demand for and price of TiO2. As a result new and innovative ways of TiO2 production are needed. READ MORE

  7. 5. On the chemical and processing stability of pharmaceutical solids : Solid form dependent water presenting capacity and process induced solid form transformation

    Author : Mina Heidarian Höckerfelt; Göran Alderborn; Stefan Ulvenlund; Uppsala universitet; []
    Keywords : ;

    Abstract : There is a need for improving our knowledge and understanding about formation mechanisms and nature of amorphous state in order to prevent the unintended presence of disorder in solid pharmaceutical products and reduce the related stability issues. The suggested theory that water binding capacity of amorphous cellulose affects the chemical stability of hydrolysis sensitive drugs in formulations with cellulose based excipients needs a clarification and water-cellulose interaction profiles need to be examined.
