4. 18. Phase Stability and Preparations of Oxide-Apatite Composites

   Författare :Erik Adolfsson; Bengt Kasemo; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; oorganisk kemi; Inorganic Chemistry;

   Sammanfattning : In the preparation of bioactive composites containing hydroxyapatite, Ca5(PO4)3(OH), and an oxide it has been a problem to prevent the hydroxyapatite from decomposing in the sintering process. This is because H2O is evolved when hydroxyapatite is heated, implying that the occupied OH- positions in hydroxyapatite structure are partly replaced by vacancies and O2- ions. LÄS MER

5. 19. Comparative studies of alkylating and N-heterocyclic compounds on different genetic endpoints with special emphasis on amplification of minisatellite sequences

   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Several mutational events are involved in the multistage process of cancer. Genetic instability of tumor DNA is shown in a variety of genetic changes such as point mutations, chromosomal aberrations, aneuploidy, DNA amplification and somatic recombination. LÄS MER
