1. Developmental disturbances of cementum induced by 1-hydroxyethylidene-1, 1-bisphosphonate (HEBP) : experimental studies on rats
Sammanfattning : By studying the mechanism(s) behind experimentally induced developmental disturbances of a tissue, it may be possible to gain information about its normal development. Cementum seems to be the least understood of the dental tissues, and there are very few studies in which its development has been experimentally altered. LÄS MER
2. Cemented Carbide Sintering : Constitutive Relations and Microstructural Evolution
Sammanfattning : Cemented carbides based on tungsten carbide and cobalt arecommonly produced by a powder metallurgy route including liquidphase sintering. The pressed compact densifies to almost halfits volume during sintering due to pore elimination. LÄS MER
3. Simulation, Measurement and Analysis of the Response of Electron- and Position Sensitive Detector
Sammanfattning : Different methods exist in relation to probing and investigating thephysical and structural composition of materials especially detectors whoseusage have become an integral part of radiation detection. The use of thescanning electron microscopy is just one of such exploratory methods. LÄS MER
4. Characterization of (Ba,Sr)TiO3 thin films for multiplier applications
Sammanfattning : (Ba,Sr)TiO3 (BSTO) and SrTiO3 (STO) parallel plate ferroelectric varactors are investigated for microwave multiplier applications.STO and BSTO exhibit low losses, high permittivity and largetunability of both permittivity and losses. All films are deposited using Pulsed Laser Deposition, magnetron sputtering and E-beam evaporation. LÄS MER
5. Consumption and loss of commercial stabilisers in polyethylene exposed to different natural environments
Sammanfattning : A procedure for the extraction and analysis of commercialstabilisers in low density and medium density polyethylene(LDPE and MDPE) films was developed and used to study theconsumption of stabilisers in polymers exposed to differentnatural environments. An ultrasonic technique was applied toextract HALS-3 (Chimassorb 944) from LDPE film and antioxidants(Irganox 1010 and Irgafos 168) from MDPE film. LÄS MER
