  1. 21. Contrast enhanced transrectal ultrasound of the prostate : An experimental and clinical study

    Författare :Else Krüger Hagen; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; Transrectal ultrasound; Onkologi; Oncology; Onkologi; radiologi; Radiology;

    Sammanfattning : The purpose of this thesis was to evaluate the diagnostic potential of a new ultrasound contrast agent,SonazoidTM, intended for use in patients with suspicion of prostate cancer.The sonographic appearance of normal prostatic vascularity in dogs was evaluated before and after injection of Sonazoid,using different Doppler flow detection modes.

  3. 22. The three-dimensional normal-distributions transform : an efficient representation for registration, surface analysis, and loop detection

    Författare :Martin Magnusson; Achim Lilienthal; Wolfram Burgard; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NDT; 3D sensing; surface representation; registration; loop detection; surface analysis; mobile robotics; localisation; mapping; Computer science; Datavetenskap; Computer and Systems Science; Data- och systemvetenskap;

    Sammanfattning : This dissertation is concerned with three-dimensional (3D) sensing and 3D scan representation. Three-dimensional records are important tools in several disciplines; such as medical imaging, archaeology, and mobile robotics. LÄS MER

  4. 23. Flow-induced Surface Defects and Ageing Behaviour of Injection-moulded Polymers

    Författare :Giovanna Iannuzzi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PP; surface defects; flow marks tiger stripes ; ageing; Injection moulding; ABS; rheological properties; degradation; surface topography; discolouration;

    Sammanfattning : Injection moulding is one of the most commonly used manufacturing methods for the production of polymer-based components such as car bumpers and other automotive details. The surface appearance of these products is of great importance since it is directly connected to the perceived quality. LÄS MER

  5. 24. Fruit wastes to biomaterials : Development of biofilms and 3D objects in a circular economy system

    Författare :Veronika Bátori; Kristiina Oksman; Högskolan i Borås; []
    Nyckelord :apple pomace; biodegradable; bioplastics; circular economy; orange waste; resource recovery; Resource Recovery; Resursåtervinning;

    Sammanfattning : To address the current plastic pollution problem, the replacement of conventional plastics with bioplastics can be considered. Although the land use of crop cultivation for bioplastics is still negligible, there is an increasing interest in the utilisation of lignocellulosic waste products for the production of bioplastics.

  7. 25. Quality Aspects of Modified Atmosphere Packaged Broccoli

    Författare :Annelie Jacobsson; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Livsmedelsteknik; Food and drink technology; heat transfer; mass transport; quality; flavour; aroma; modified atmosphere packaging; broccoli;

    Sammanfattning : The modified atmosphere packaging (MAP) of vegetables is used with the aim of prolonging the shelf-life of the packaged produce. The packaging material consists of a permeable film and as a result of the respiration of the produce and gas diffusion through the film, the O2 decreases and the CO2 increases inside the package.
