  1. 1. Integration of Non-synchronous Generation - Frequency Dynamics

    Författare :Johan Björnstedt; Industriell elektroteknik och automation; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Frequency control; Frequency dynamics; Frequency response; Non-synchronous generation; Power system; Synthetic inertia; Wind power;

    Sammanfattning : Traditionally the predominant generation has been large synchronous generators providing the system inertia. Nowadays when wind power and other non-synchronously connected units displaces this synchronous generation, the system inertia is reduced. Hence higher rate of change of frequency and larger frequency deviations are expected. LÄS MER

  2. 2. Islet insulin secretory patterns in diabetes and the role of UCP2

    Författare :Jian-Man Lin; Valdemar Grill; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; type 1 diabetes; type 2 diabetes; NOD; GK; congenes; KKAy; human; islet; glucose; insulin release; oscillation; frequency; amplitude; oxidation; respiration; UCP2; western blot; Cellbiologi; Cell biology; Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

    Sammanfattning : During development of type 1 and type 2 diabetes plasma insulin patterns are altered. Since the islet insulin release pattern has been implicated in this development, insulin secretion from single islets was studied and linked to the islet protein levels of uncoupling protein-2 (UCP2).

  3. 3. Thick Frequency Selective Structures

    Författare :Björn Widenberg; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; acoustics; Elektromagnetism; optik; akustik; optics; Electromagnetism; Energy Saving Window; Radome; Finite Elemente Method; Frequency Selective Structure; Mode Matching Technique;

    Sammanfattning : This thesis presents a new method that can handle a general thick Frequency Selective Structure (FSS), that consists of an arbitrary number of aperture layers and dielectric layers. The method is based on the Mode Matching Technique (MMT) and the finite element method (FEM). The thesis consists of a General Introduction and five scientific papers. LÄS MER

  5. 5. Congenital Heart Disease, Type 1 and Type 2 Diabetes Mellitus

    Författare :Anna Björk; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Congenital Heart Disease; Diabetes Mellitus; Type 1 Diabetes Mellitus; Type 2 Diabetes Mellitus; Mortality; Morbidity;

    Sammanfattning : Worldwide, 1% of all live born children are born with a congenital heart disease (CHD) and currently >95% reach adulthood due to better diagnostics and medical care. At the same time, Diabetes Mellitus (DM), type 1 (T1DM) and type 2 (T2DM), is increasing worldwide. LÄS MER
