    Sammanfattning : This thesis investigates the ecological and evolutionary implications of a recent secondary contact between two closely related bird species: collared (Ficedula albicollis) and pied (F. hypoleuca) flycatchers. LÄS MER

  4. 3. Distal femur fracture in the elderly patient

    Författare :Martin Paulsson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Distal femur fracture; Geriatric patients; Weight-bearing; Recovery; Secondary displacement; Minimally invasive plate osteosynthesis MIPO ; Fracture alignment; Fracture classification;

    Sammanfattning : Studies on the epidemiology of distal femur fractures show a vast increase in low-energy trauma-associated fractures in older ages. Age-related changes in bones lead to loss of bone matrix and increased porosity, which entails an increased risk for fractures and different fracture patterns than in younger individuals. LÄS MER

  5. 4. Capturing the antecedents and aftermath of a family business process : The entrepreneurial journey of a displaced agricultural family in Colombia

    Författare :Enrique Sandino Vargas; Leona Achtenhagen; Daniel Pittino; Marcela Ramirez-Pasillas; Bengt Johannisson; Jönköping University; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; agricultural family; Colombia; displacement; entrepreneurial journey; entrepreneurial process; familiness; family; family business; family capital; family-life context; family habitus; family business habitus; guerrilla; habitualization; habitus; farm; land; rural; violence;

    Sammanfattning : This study examines a displaced agricultural family during its entrepreneurial journey in Colombia using a single case study, following an inductive and interpretivist approach. The main objective of the dissertation is to explain how family interactions, historical events, and context influence the decision to start and potentially reactivate an agricultural family business.

  7. 5. On Active Secondary Suspension in Rail Vehicles to Improve Ride Comfort

    Författare :Anneli Orvnäs; Sebastian Stichel; Rickard Persson; Roger Goodall; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rail vehicle; active secondary suspension; ride comfort; sky-hook damping; H∞ control; multi-body simulations; on-track tests; Järnvägsgruppen - Gröna tåget; Järnvägsgruppen - Gröna tåget; Järnvägsgruppen - Fordonsteknik; Järnvägsgruppen - Fordonsteknik;

    Sammanfattning : One way to make rail vehicles a competitive means of transportation is to increase running speed. However, higher speeds usually generate increased forces and accelerations on the vehicle, which have a negative effect on ride comfort. With conventional passive suspension, it may be difficult to maintain acceptable passenger comfort. LÄS MER
