  1. 11. Situation analysis for fighter aircraft combat survivability

    Författare :Tina Erlandsson; Lars Niklasson; Göran Falkman; Silvia Coradeschi; Per-Johan Nordlund; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fighter aircraft; situation analysis; combat survival; decision support; uncertainty; Datalogi; Computer and Systems Science; Teknik;

    Sammanfattning : Fighter pilots operate in environments where an erroneous decision may have fatal consequences. A tactical decision support system (TDSS) could aid the pilots to analyze the situation and make correct decisions. The TDSS can, for instance, highlight important information and suggest suitable actions. LÄS MER

  2. 12. Semiparametric survival models for routine register data

    Författare :Frank Eriksson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Survival; transformation; clustered; likelihood; random effects; case-cohort; routine register; semiparametric; clustered;

    Sammanfattning : Routine registers offer researchers opportunities to carry out studies of covariate effects on lifetimes of rare diseases otherwise infeasible because of the large cohorts required. Familial relationships necessary for analysis of environmental or genetic factors can be identified by record linking. LÄS MER

  3. 13. Morale in very old people : With focus on stroke, depression and survival

    Författare :Johan Niklasson; Yngve Gustafson; Hugo Lövheim; Aase Wisten; Sölve Elmståhl; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Morale; aged 80 and over; Sweden and Finland; Psychometrics testing; Feasibility studies; Quality of Life; Stroke; Depressive disorders; Geriatric psychiatry; Salutogenic factor; Survival; Longevity; Future-oriented optimism;

    Sammanfattning : Background: Morale is a multidimensional concept, often defined as a future-oriented optimism or pessimism regarding the problems and opportunities associated with ageing. Very old people, older than 80 years, constitute an age group that is expected to increase in Europe from 4.7% of the general population today to 12. LÄS MER

  4. 14. Cancer of the Colon and Rectum : Population Based Survival Analysis and Study on Adverse Effects of Radiation Therapy for Rectal Cancer

    Författare :Helgi Birgisson; Lars Påhlman; Bengt Glimelius; Ulf Gunnarsson; Ragnar Hultborn; Uppsala universitet; []
    Nyckelord :Surgery; cancer; colon; rectal; colorectal; survival; radiation therapy; second cancer; adverse effects; Kirurgi;

    Sammanfattning : The Swedish Cancer Register was used to determine the relative survival rate in colon and rectal cancer and to estimate the occurrence of second cancers related to radiation therapy for rectal cancer. The Swedish Hospital Discharge Register and hospital records were used to estimate the rate of late adverse effects due to radiation therapy for rectal cancer. LÄS MER

  5. 15. Genomic profiling of breast cancer by microarray-based technology and bioinformatics

    Författare :Johan Staaf; Bröstcancer-genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Survival; Prognostic predictor; Gene Expression; ERBB2; HER2; Microarray; Copy Number Analysis; CGH; aCGH; Amplification; Gene expression analysis;

    Sammanfattning : Cancer is a genetic disease that arises when a cell acquires unlimited growth potential through a series of mutational events, which target genes essential for normal cell control and maintenance. Breast cancer is one of the most frequent malignancies in women worldwide, and it is characterized by heterogeneous tumor biology, histological subtypes, variable prognosis and variable responsiveness to treatment.
