  2. 1. Analysis of Human Brain MRI : Contributions to Regional Volume Studies

    Author : Richard Nordenskjöld; Joel Kullberg; Elna-Marie Larsson; Lars Johansson; Håkan Ahlström; Göran Starck; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MRI; Brain; Volume; Hemisphere; Intracranial volume; Image analysis; Computerized Image Analysis; Datoriserad bildanalys;

    Abstract : Many disorders are associated with regional brain volumes. The analysis of these volumes from MR images often requires sequential processing steps such as localization and delineation. READ MORE

  4. 2. Macroscopic Volume and Free Volume of Polymer Blends and Pressure-densified Polymers

    Author : Marcus Schmidt; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; free-volume theories; refractive index; Lorentz-Lorenz equation; loss tangent; Avrami equation; freezing fractions; copolymers; polymer blends; pressure dilatometry; Tait equation of state; free-volume distributions; pressure-densified polymers; entropy of melting; dynamic-mechanical analysis; positronium; positron annihilation; free volume; cavity size; polymers; bulk modulus; PVT; phase separation; compressibility; thermal expansivity;

    Abstract : The macroscopic volume V as a function of pressure P and temperature T is obtained from PVT measurements. PVT data is sensitive to the state of polymers and changes therein. Moreover, PVT data gives access to the free-volume fraction. READ MORE

  5. 3. Modelling of laser-based powder bed fusion for bulk metallic glass formation

    Author : Johan Lindwall; Andreas Lundbäck; Albert To; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material Mechanics; Materialmekanik;

    Abstract : The work presented in this thesis aims to develop a modelling approach to predict crystalline phase evolution in bulk metallic glass during additive manufacturing with laser-based powder bed fusion (PBF-LB). Metallic glasses are non-crystalline metallic materials that generally possess exceptional properties because of its amorphous struc-ture. READ MORE

  6. 4. "To pee or not to pee?" : A study of the voiding pattern and urinary flow in healthy children

    Author : Sven Mattsson; Kelm Hjälmås; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : En strävan inom pediatriken är att finna så enkla och för barnet så skonsamma undersökningsmetoder som möjligt. Särskilt vid urodynamiska undersökningar är.bamets medverkan en nödvändighetför en tillförlitlig bedömning av resultatet. READ MORE

  7. 5. Biological Rhythms of Pancreatic Secretion in Young Pigs with empahasis to the time around weaning

    Author : Mary-Jane Sebabatso Thaela; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Volume; Ultradian; Protein; Pancreas; Pig; IRCT; Insulin; Infradian; Glucose; Circadian; Chymotrypsin; Biologic week and Half-week; Chronome; Animal physiology; Djurfysiologi;

    Abstract : When the time structure (chronome) of pancreatic secretion was studied after weaning in 5-week-old pigs, the zero-amplitude (no-rhythm) assumption was rejected for the about-weekly (circaseptan, CS) and about-half-weekly (circasemiseptan, CSS) chronome components. When the data were assessed individually on a day-to-day basis, a 24-hour component was suggested (P. READ MORE
