  1. 1. Svenska kyrkans sociala arbete – för vem och varför? : En religionssociologisk studie av ett diakonalt dilemma

    Författare :Charlotte Engel; Thorleif Pettersson; Jonas Alwall; Jonas Bromander; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Sociology of religion; Religionssociologi; Diakoni; socialt arbete; Svenska kyrkan; marginalisering; marginaliserade grupper; sekularisering; religionssociologi; Sociology of religion; Religionssociologi; religionssociologi; religionssociologi; Religion Theology;

    Sammanfattning : The main purpose of this dissertation has been to investigate how well diaconal work in seven chosen parishes corresponds to an official definition of the diaconal task of the Church of Sweden as above all to represent and direct activities towards the most disadvantaged and/or marginalised groups in society, a definition that well corresponds to the general expectations of the Swedish people regarding the role of the Church. The empirical ground for the dissertation comes from diaconal inventories built mainly on a comprehensive interview material with parish workers and appointed representatives in the chosen parishes.

  3. 2. High-Frequency ECG in Ischemic Heart Disease

    Författare :Jonas Pettersson; Avdelningen för klinisk genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiology; Clinical physics; high-frequency QRS components; electrocardiogram; myocardial infarction; myocardial ischemia; Ischemic heart disease; tomography; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering;

    Sammanfattning : Analysis of high-frequency QRS components (HF-QRS) is one of the emerging methods for increasing the diagnostic performance of the electrocardiogram (ECG). The overall objective of the thesis is to investigate whether analysis of HF-QRS has the ability to provide information about ischemic heart disease and so serve as an adjunctive diagnostic tool in several clinical situations.

  4. 3. Biosynthetic conduits and cell transplantation for neural repair

    Författare :Jonas Pettersson; Lev Novikov; Liudmila Novikova; Mikael Wiberg; Lars Dahlin; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Spinal cord injury; Peripheral nerve injury; Nerve graft; Biosynthetic conduit; Nerve tissue engineering; Neural prosthesis; Neuroscience; Neurovetenskap; neurologi; Neurology; neurokirurgi; Neurosurgery;

    Sammanfattning : Spinal cord injury results in complete failure of the central neurons to regenerate and is associated with cyst formation and enlargement of the trauma zone. In contrast to the spinal cord, axons in the injured peripheral nerve have the capacity to undergo some spontaneous regeneration. LÄS MER

  5. 4. Modelling Band Gap Gradients and Cd-free Buffer Layers in Cu(In,Ga)Se2 Solar Cells

    Författare :Jonas Pettersson; Charlotte Platzer-Björkman; Marika Edoff; Marc Burgelman; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; CIGS; Thin film solar cells; Electrical modelling; Alternative buffer layers; Gallium gradients; Simulations; Electrical characterization; Metastabilities; Light-soaking; Hall measurements; Persistent photoconductivity; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

    Sammanfattning : A deeper understanding of Cu(In,Ga)Se2 (CIGS) solar cells is important for the further improvement of these devices. This thesis is focused on the use of electrical modelling as a tool for pursuing this aim. Finished devices and individual layers are characterized and the acquired data are used as input in the simulations. LÄS MER

  7. 5. Effects of trace elements in biodiesel on the performance of diesel oxidation catalysts in heavy-duty vehicles

    Författare :Jonas Granestrand; Lars Pettersson; Todd J. Toops; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diesel Oxidation catalyst; heavy-duty vehicles; catalyst deactivation; biodiesel; NAP-XPS; XANES; Phosphorus; alkali metals; Pt Pd Al2O3; Chemical Engineering; Kemiteknik;

    Sammanfattning : To reduce net greenhouse gas emissions, a shift towards adoption of biofuels is ongoing in the transport sector. Heavy-duty diesel vehicles are equipped with aftertreatment equipment, comprising of catalysts and filters, and how this equipment is affected by the use of biofuels is not yet fully understood.
