  1. 1. Suspensions of Calcium Phosphate : Interactions of milk proteins to hydroxyapatite

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Ying Chen; [2023]
    Nyckelord :Calcium fortification; Milk proteins interactions; Colloid chemistry; Food technology; engineering and nutrition; Agriculture and Food Sciences;

    Sammanfattning : Capolac is a product containing hydroxyapatite (HA) from Arla Food Ingredients, to be used for calcium fortification. The adsorption of casein and whey proteins onto the Capolac was investigated, aiming to solve the sedimentation problem of this insoluble calcium phosphate. LÄS MER

  3. 2. On-chip characterization of hydroxyapatite with different topography

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för materialvetenskap

    Författare :Maja Grape; [2022]
    Nyckelord :biomaterials; calcium-deficient hydroxyapatite; microfluidic systems;

    Sammanfattning : Biomaterials are defined as non-viable materials whose functions strives to interact with biological systems, this makes biomaterials suitable for medical devices and applications. Biomaterials biological properties must be thoroughly investigated and evaluated in order to be approved for clinical usage. LÄS MER

  4. 3. BJÖRNGRAVEN FRÅN KARATS En explorativ studie av arkeologiskt benmaterial och dess betydelse i den samiska religionen

    Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Matilda Sundström; [2021-03-11]
    Nyckelord :Bear grave; FTIR; Archeological Bone; PVAc; Sámi religion;

    Sammanfattning : This thesis is an exploratory study of a Sámi Bear Grave found on a small island in lake Karats, Jokkmokk in 1983. The grave was excavated in 1986 and put on display at Ájtte, Swedish Mountain and Sámi Museum in Jokkmokk. LÄS MER

  5. 4. Synchrotron X-ray Tomography Study of Bone-implant Integration

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Ornella Lohéac; [2021]
    Nyckelord :Bone-implant; Digital volume correlation; Micro-computed tomography; PEEK; Synchrotron; Technology and Engineering;

    Sammanfattning : Implant loosening is a recurring problem in the field of orthopedics, typically resulting in a physical and financial burden for the patient. Proper integration of orthopedic implants within host bones is a fundamental requirement for the successful function and limited risk of failure of implants which, in-vivo, must support various loading conditions.

  7. 5. Modeling of bone cell adhesion on bio-compatible surfaces, Modellering av bencellers adsorption på biokompatibla ytor

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Agnes Berg; Ebba Edqvist; [2020]
    Nyckelord :;

    Sammanfattning : A mathematical model is presented to describe osteoblast adsorption on calcium-deficient hydroxyapatite, focusing on adsorption rate, cell survival and protein pre-incubation time. The proposed model is fitted to experimental data sets by fine-tuning the parameters for adsorption rate and cell survival. LÄS MER
