The use of ground-source heat pumps for heating buildings and domestic hot water in dwellings is increasing rapidly in Sweden. The heat pump extracts heat from the ground by a U-pipe in a vertical borehole. In order to reduce the electricity demand in the system, the combination with solar collectors is introduced. This system may be designed in many ways and the advantages differ a lot. Solar hea

Objectives. To clarify if an adaptive current stimulation protocol, in which current amplitude is modulated during continuous stimulation, provides better efficacy than constant current stimulation protocol with respect to analgesia caused by individualized stimulation in rat periaqueductal gray matter (PAG) /dorsal raphe nuclei (DRN). Approach. Ultrathin microelectrodes adapted for recording (n =

Background: Previous studies have reported an increased fracture risk after bariatric surgery. Objective: To investigate the association between different bariatric surgery procedures and fracture risk. Methods: Incidence rates and hazard ratios for fracture events were analysed in the Swedish Obese Subjects study; an ongoing, nonrandomized, prospective, controlled intervention study. Hazard ratio

Vår grupp studerar olika höftsjukdomar med debut i barndomen och deras association med framtida höftbesvär och artros. 1) Höftdysplasi är en omogenhet i höftleden som innefattar patientgrupper från nyfödda till vuxna. 2) Femuroacetabulärt impingement (FAI) är en anatomisk avvikelse i höftleden. 3) Fysiolys, är en glidning i höftkulans tillväxtzon hos tonåringar som oftast är: a. kronisk eller Our group investigates hip joint diseases that start during childhood but may result in impaired function and OA in adulthood. 1) Hip dysplasia ranges from congenital dislocation to dysplasia in adults. 2) Femuroacetabulärt impingement (FAI) is developmental anatomical deformity. 3) Slipped Capital Femoral Epiphysis (SCFE) is a slip in the growth plate of the femoral head, most commonly: a.

Avdelningen Studieadministrativa system ansvarar bland annat för systemen Ladok, Lubas och SUNET Survey. Avdelningen arbetar med systemförvaltning samt systemadministration och ger utbildning och service till användarna.

This master thesis addresses the electrically powered assisted bicycle (EPAC) as a future low-carbon commuting option and its market. The purpose of the report is to evaluate whether the EPAC can be used to improve the climate performance of the transport sector and to assess the outlook for the Swedish EPAC market. The EPAC is compared to the bicycle, car, bus and train and assessed thereafter. T

The global pandemic has initially negatively influenced the financial markets all over the world. As a consequence, the volatility in the stock markets increased and investors have experienced great monetary losses. In addition, the volatility spillover has increased between different markets and assets, which additionally amplifies the negative influence by the pandemic. This motivates the search

We employ quantum thermodynamics to develop new paradigms for energy conversion and quantum devices at the nanoscale, where thermal and quantum fluctuations may conspire to profoundly alter the physical properties. We set focus on interacting few- or many-particle quantum systems where effects of quantum correlations, fluctuation statistics and quantum coherence lead to fundamentally new physics w
