    Sammanfattning : Solar irradiation is a vast and plentiful source of energy. The use of photovoltaic (PV) devices to convert solar energy directly to electrical energy is an elegant way of sustainable power generation which can be distributed or in large PV plants based on the need. LÄS MER

  3. 2. Studying abroad : exploring mobility, expectations and experiences among mobile students

    Författare :Per A. Nilsson; Kerstin Westin; Dieter K. Müller; Jan-Henrik Nilsson; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; student mobility; inbound; outbound; exchange students; Sweden; Social and Economic Geography; kulturgeografi;

    Sammanfattning : This thesis deals with the experiences and outcomes of temporarily studying abroad, via follow-up studies, aiming to explore international student mobility with a focus on the individual’s perspective. The specific research questions, dealing with the individual students’ expectations and experiences, are addressed in three papers. LÄS MER

  4. 3. Tinnitus – an acceptance-based approach

    Författare :Vendela Zetterqvist (f.d. Westin); Gerhard Andersson; Per Carlbring; Mary Rudner; Steven Linton; Linköpings universitet; []
    Nyckelord :Tinnitus; tinnitus interference; acceptance; defusion; Acceptance and Commitment Therapy; Tinnitus; tinnitusbesvär; acceptans; defusion; Acceptance and Commitment Therapy; MEDICINE; MEDICIN;

    Sammanfattning : Tinnitus is a highly prevalent health condition creating moderate or severe interference on mood, sleep and daily functioning for a group of those affected. The aims of this thesis were 1) to explore the role of acceptance and psychological flexibility in understanding tinnitus interference both experimentally and with a longitudinal design 2) to evaluate the immediate and long-term outcomes of an acceptance based behaviour therapy (Acceptance and Commitment Therapy; ACT) in the treatment of people with tinnitus and, 3) to investigate the relationship between treatment outcome and processes assumed to be the active ingredients of treatment (acceptance and cognitive defusion).

  5. 4. Studies of epigenetic deregulation in parathyroid tumors and small intestinal neuroendocrine tumors

    Författare :Elham Barazeghi; Gunnar Westin; Peter Stålberg; Per Hellman; Christofer Juhlin; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Epigenetics; 5hmC; TET1; TET2; parathyroid tumors; SI-NET; RRBS; PTPRM;

    Sammanfattning : Deregulation of the epigenome is associated with the initiation and progression of various types of human cancers. Here we investigated the level of 5-hydroxymethylcytosine (5hmC), expression and function of TET1 and TET2, and DNA methylation in parathyroid tumors and small intestinal neuroendocrine tumors (SI-NETs).

    Sammanfattning : Endocrine tumors arise from endocrine glands. Most endocrine tumors are benign but malignant variants exist. Several endocrine neoplasms display loss of parts of chromosome 11 or 18, produce hormones and responds poorly to conventional chemotherapeutics. The multiple endocrine neoplasia syndromes are mainly confined to endocrine tumors. LÄS MER
