  1. 1. Footing with Settlement-Reducing Piles in Non-Cohesive Soil

    Författare :Duc Long Phung; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Although the design concept based on the idea of limiting the settlement of footings by settlement-reducing piles is gaining more and more support, there have been very few experimental studies of the behaviour of piled footings in non-cohesive soil. The influences of the contact between the pile cap and the soil on the capacity and the load-settlement behaviour of a piled footing are considerable but this has not been well understood. LÄS MER

  3. 2. Genetics and biomarkers of frailty : towards individualized management of the frailty syndrome

    Författare :Ka Long Jonathan Mak; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Frailty is an age-related, dynamic state of multisystem physiological decline and is a strong predictor of disability and mortality. To move towards an individualized management of frailty, a better understanding of its biological underpinnings and an early identification of frail older adults are necessary. LÄS MER

  4. 3. Thermal modelling and evaluation of borehole heat transfer

    Författare :Saqib Javed; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ground source heat pump; fluid temperature; borehole; short-term; thermal response test; groundwater-filled; optimization; load aggregation; simulation; recovery; step-response; long-term; ground heat exchanger; times; design; ground-coupled;

    Sammanfattning : The use of ground source heat pump systems to provide heating and cooling inbuildings has increased greatly in the last decade or so. These systems have a highpotential for energy efficiency, which has environmental and economicadvantages. LÄS MER

  5. 4. Diversification and strategic, long-distance partnerships : Bofors' struggle through times of crisis and uncertainty

    Författare :Cecilia Beckmann; Mats Lundmark; Eva Gustavsson; Karl-Johan Lundqvist; Örebro universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Diversification; partnership; collaboration; proximity; institutional environment; industrial cities;

    Sammanfattning : This is a case study that aims to explain how the company Bofors in Karlskoga, Sweden, struggled through three periods of crisis or uncertainty, while remaining innovative. It begins in the late 19th century and ends in the early 21st century after Bofors had been divested. LÄS MER

  7. 5. Long shifts, short rests and vulnerability to shift work

    Författare :John Axelsson; Torbjörn Åkerstedt; Ulf Lundberg; Phil Tucker; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Sleep; alertness; sleepiness; shiftwork; compressed working hours; long shifts; 12h shifts; quick returns; quick change-overs; tolerance; gender; Psychology; Psykologi;

    Sammanfattning : At the same time as many urban economies are developing into 24-hour societies it is becoming increasingly popular amongst shift workers to compress their working hours. This is done by working longer shifts (>8h) and/or restricting free time (... LÄS MER
