  3. 2. Modelling the Variability of Bending Strength in Structural Timber - Length and Load Configuration Effects

    Författare :Tord Isaksson; Avdelningen för Konstruktionsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; code; reliability-based design; Weibull; test standard; load configuration effect; length effect; weak section; machine grading; visual grading; variability; Structural timber; bending strength; simulation; monte carlo simulation.; Building construction; Byggnadsteknik;

    Sammanfattning : The load carrying capacity of a beam of structural timber is dependent both on the span of the beam and the type of loading. The longer the beam and the more uniform the moment distribution, the lower the load carrying capacity. This phenomenon is due to the variability of material properties within a piece of timber.

  5. 4. Leg length discrepancy and femoral offset after total hip arthroplasty : clinical and radiological studies

    Författare :Sarwar Mahmood; Arkan Sayed-Noor; Sead Crnalic; Gösta Ullmark; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Total hip arthroplasty; leg flength discrepancy; femoral offset; WOMAC; quality of life; complication; radiographic measurements; acetabular cup; inclination; anteversion; Orthopaedics; ortopedi;

    Sammanfattning : Every year, about 1 million patients worldwide and 16000 patients in Sweden undergo total hip arthroplasty (THA). This surgical intervention is considered a successful, safe and cost-effective procedure to regain pain-free mobility and restore hip joint function in patients suffering from severe hip joint disease or trauma.

  7. 5. Risk factors and adverse pregnancy outcomes in small-for-gestational-age births

    Författare :Britt Clausson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Obstetrics and gynaecology; Pregnancy; birthweight; fetal growth retardation; small-for-gestational age; maternal anthropometrics; genetic; caffeine; stillbirth; postterm pregnancy; birthweight standard; Obstetrik och kvinnosjukdomar; Obstetrics and women s diseases; Obstetrik och kvinnosjukdomar; Obstetrics and Gynaecology; obstetrik och gynekologi;

    Sammanfattning : The studies were undertaken to evaluate risk factors and outcomes in small-for-gestational-age (SGA) births, in cohort studies using the population-based Swedish Birth, Twin and Education Registers. A cohort study of pregnant women from Uppsala County evaluated the effect on birthweight by caffeine. LÄS MER
